innoextract(1) General Commands Manual innoextract(1) NAME innoextract - tool to extract installers created by Inno Setup SYNOPSIS innoextract [--extract] [--lowercase] [options] [--] installers ... innoextract --list [options] [--] installers ... innoextract --test [options] [--] installers ... DESCRIPTION innoextract is a tool that can extract installer executables created by Inno Setup. innoextract will extract files from installers specified on the command line. To extract a multi-part installer with external data files, only the exe- cutable (.exe) file needs to be given as an argument to innoextract. OPTIONS SUMMARY Here is a short summary of the options available in innoextract. Please re- fer to the detailed documentation below for a complete description. Generic options: -h --help Show supported options -v --version Print version information --license Show license information Actions: -t --test Only verify checksums, don't write anything -e --extract Extract files (default action) -l --list Only list files, don't write anything --list-sizes List file sizes --list-checksums List file checksums -i --info Print information about the installer --list-languages List languages supported by the installer --gog-game-id Determine the GOG.com game ID for this installer --show-password Show password check information --check-password Abort if the password is incorrect -V --data-version Only print the data version Modifiers: --codepage CODEPAGE Encoding for ANSI strings --collisions ACTION How to handle duplicate files --default-language Default language for renaming --dump Dump contents without converting filenames -L --lowercase Convert extracted filenames to lower-case -T --timestamps TZ Timezone for file times or "local" or "none" -d --output-dir DIR Extract files into the given directory -P --password PASSWORD Password for encrypted files --password-file FILE File to load password from -g --gog Process additional archives from GOG.com installers --no-gog-galaxy Don't re-assemble GOG Galaxy file parts -n --no-extract-unknown Don't extract unknown Inno Setup versions Filters: -m --exclude-temp Don't extract temporary files --language LANG Extract only files for this language --language-only Only extract language-specific files -I --include EXPR Extract only files that match this path Display options: -q --quiet Output less information -s --silent Output only error/warning information --no-warn-unused Don't warn on unused .bin files -c --color[=ENABLE] Enable/disable color output -p --progress[=ENABLE] Enable/disable the progress bar OPTIONS -- Treat all arguments after this one as files, even if they begin with a dash. --check-password Abort processing if the password provided using the --password or --password-file option does not match the checksum stored in the in- staller. The password checksum used for this check can be retrieved using the --show-password option. --codepage CODEPAGE Non-Unicode versions of Inno Setup store strings in an unspecified encoding. By default, innoextract will guess the encoding from the installer's language list, falling back to Windows-1252. This option can be used to override that guess by specifying a non-zero Windows codepage number to use. On non-Windows platforms, innoextract will ignore the system locale and always use UTF-8 as the filesystem and standard output encoding - the --codepage option only changes the input encoding. However, using codepage number "65001" instructs innoextract to assume all strings are already encoded as UTF-8 and to output them without con- version. This option has no effect with Unicode-enabled installers, which al- ways use UTF-16LE. Invalid UTF-16 data is represented using the WTF-8 encoding which is a straightforward extension of UTF-8 to rep- resent unpaired UTF-16 surrogate code units. --collisions ACTION Inno Setup installers can contain duplicate files with the same name. This option tells innoextract what to do when such a colli- sions is encountered. Valid actions are: "overwrite" Extract only one of the colliding files. The choice is done similar to how Inno Setup overwrites files during installa- tion. This is the default. "rename" Rename files that would be overwritten using the "overwrite" action by appending a suffix comprised of the file's lan- guage, its architecture, the component it belongs to and/or a number to make the filename unique. The language suffix (if applicable) is also appended to the default file that would have been extracted with the "overwrite" action. "rename-all" Rename all colliding files by appending a suffix comprised of the file's language, its architecture, the component it be- longs to and/or a number to make the filename unique. The complete suffix is appended to both files that would have been overwritten using the "overwrite" action and to those that would have overwritten other files. "error" Exit when a collision is detected. Rename rules: 1. If the component is not the same for all files in the collision set (all files with the same filename), "#" (without quotes) fol- lowed by the component id is appended to all files that are specific to a single component. 2. If the language is not the same for all files in the collision set, "@" (without quotes) followed by the language id is appended to all files that are specific to a single language unless that lan- guage matches the default language specified by the --default-lan- guage. While the suffix is omitted for the default language, no num- bered suffix is added in it's place unless needed to make the file- name unique. 3. If the architecture is not the same for all files in the colli- sion set, "@32bit" or "@64bit" (without quotes) is appended to all files that are specific to a single architecture. 4. If no suffix was added by the previous steps, or if the filename is not yet unique, "$" (without quotes) followed by the lowest inte- ger (starting at 0) to make the filename unique is appended. With the "rename" action, steps 1 and 3 are only applied to files that would have been overwritten by the "overwrite" action while "rename-all" applies them to all files in the collision set. -c, --color[=ENABLE] By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable color output accordingly. Specifically, colors will be enabled if both stdout and stderr point to a TTY, the TERM environment variable is not set to "dumb" and the NO_COLOR environment variable is unset. Pass 1 or true to --color to force color output. Pass 0 or false to never output color codes. -V, --data-version Print the Inno Setup data version of the installer and exit immedi- ately. The version printed using this option is the one stored in the setup file and can differ from the version printed with other actions as the stored data version is not always correct. This option can be used to determine if a file is an Inno Setup in- staller without loading any compressed headers. This option cannot be combined with any other action. --default-language LANG Set a language as the default. With --collisions=overwrite (the default) this will change the choice of which file to keep to always prefer the given language. In effect, --default-language behaves almost like --language, except that files are extracted for all languages if they have different names. When using the --collisions=rename option, --default-language chooses a language for which the files should keep the original name if possible. --dump Don't convert Windows paths to UNIX paths and don't substitute con- stants in paths. When combining --dump with --extract innoextract will not ensure that the paths don't point outside the destination directory. Use this option with caution when handling untrusted files. -m, --exclude-temp Don't extract files that would have been deleted at the end of the install process. Such files are marked with [temp] in the file list- ing. This option takes precedence over --include and --language: tempo- rary files are never extracted when using the --exclude-temp, even if they match the selected language or include expressions. -e, --extract Extract all files to the current directory. This action is enabled by default, unless one or more of the --list, --list-sizes, --list-checksums, --test, --list-languages, --gog-game-id, --show-password or --check-password actions are specified. By default innoextract will continue after encountering file check- sum errors. The --extract option can be combined with --test to abort on checksum errors. -n, --no-extract-unknown By default innoextract will try to extract installers with an un- known Inno Setup data version by treating it as the closest known version. This option tells innoextract to abort instead. -g, --gog Try to process additional .bin files that have the same basename as the setup but are not actually part of the Inno Setup installer. This is the case for newer multi-part GOG.com installers where these .bin files are RAR archives, potential encrypted with the MD5 check- sum of the game ID (see the --gog-game-id option). Extracting these RAR archives requires rar, unrar or lsar/unar com- mand-line utilities to be in the PATH. The --list, --test, --extract and --output-dir options are passed along to unrar/unar, but other options may be ignored for the RAR files. For multi-part RAR archives, the --test requires a writable output directory for temporary files which can be specified using the --output-dir option. If the output directory does not exist it will be created and then removed after testing is done. Parent di- rectories are not created. Temporary files created inside the direc- tory are always removed. Note that is option is geared towards GOG.com installers. Other in- stallers may come be bundled with different extraneous .bin which this option might not be able to handle. This option also forces re-assembly of GOG Galaxy file parts. See the --no-gog-galaxy option for details. --no-gog-galaxy Some GOG.com installers contain files in GOG Galaxy format (split into multiple parts that are individually compressed) which are re- assembled using post-install scripts. By default innoextract will try to re-assemble such files if it detects a GOG.com installer. This option disables that. GOG.com installers are detected using the publisher and URL fields in the setup headers. Use the --gog option to force reassembly for all installers. --gog-game-id Determine the ID used by GOG.com for the game contained in this in- staller. This will only work with Galaxy-ready GOG.com installers. This option can be combined with --silent to print only the game ID without additional syntax that would make consumption by other scripts harder. The --gog-game-id action can be combined with --list, --test, --ex- tract and/or --list-languages. If --silent and --gog-game-id are combined with --list and/or --list-languages, the game ID (or an empty line) will be printed on it's own line before the file list but after the language list. For newer multi-part GOG.com installers the .bin files are not part of the Inno Setup installer but instead are RAR archives. Some of these RAR files are encrypted, with the password being the MD5 checksum of the game ID: innoextract --gog-game-id --silent setup_....exe | md5sum | cut -d ' ' -f 1 -h, --help Show a list of the supported options. -I, --include EXPR If this option is specified, innoextract will only process files whose path matches EXPR. The expression can be either a single path component (a file or directory name) or a series of successive path components joined by the OS path separator (\ on Windows, / else- where). The expression is always matched against one or more full path com- ponents. Filtering by parts of filenames is currently not supported. Matching is done case-insensitively. EXPR may contain one leading path separator, in which case the rest of the expression is matched against the start of the path. Other- wise, the expression is matched against any part of the path. The --include option may be repeated in order allow files matching against one of multiple patterns. If --include is not used, all files are processed. -i --info This is a convenience option to enable all actions that print infor- mation about the installer. Scrips should not rely on the output format with this option and should instead enable the individual actions instead. Currently this option enables --list-languages, --gog-game-id and --show-password. --language LANG Extract only language-independent files and files for the given lan- guage. By default all files are extracted. To also skip language-independent files, combine this option with --language-only. --language-only Only extract files that are language-specific. This option can be combined with --language to only extract the files of a specific language. --license Show license information. -l, --list List files contained in the installer but don't extract anything. This action also enables the --list-sizes action unless either --quiet or --silent is specified. This option can be combined with --silent to print only the names of the contained files (one per line) without additional syntax that would make consumption by other scripts harder. The --list action can be combined with --test, --extract, --list-languages and/or --gog-game-id to display the names of the files as they are extracted even with --silent. --list-checksums List checksums for files contained in the installer. This option implies the --list action and can be combined with the --list-sizes option to print both the size and checksum for each file. With --silent the file checksum will be printed at the start of the line (but after the file size if enabled with the --list-sizes op- tion) followed by a space. Otherwise the checksum is printed after the file name. The checksum type can be one of Adler32, CRC32, MD5 or SHA-1 and is printed in fron of the checksum hash followed by a space. Adler32 and CRC32 checksums are printed as "0x" followed by the 32-bit hexa- decimal value. Different files in the same installer can have different checksum types if GOG Galaxy file part reassembly is not disabled using the --no-gog-galaxy option. --list-languages List languages supported by the installer. This option can be combined with --silent to print only the identi- fiers of the languages (one per line) followed by a space and then the language name, without additional syntax that would make con- sumption by other scripts harder. The --list-languages action can be combined with --list, --test, --extract and/or --gog-game-id to display the available languages before doing anything else. If --silent and --list-languages are combined with --list and/or --gog-game-id, the languages list will be terminated with an empty line and will precede both the game ID and files list. --list-sizes List uncompressed sizes for files contained in the installer. This option implies the --list action and can be combined with the --list-checksums option to print both the size and checksum for each file. With --silent the file size in bytes will be printed at the start of the line followed by a space. Otherwise the size is printed after the file name in a human-friendly format. -L, --lowercase Convert filenames stored in the installer to lower-case before ex- tracting. -d, --output-dir DIR Extract all files into the given directory. By default, innoextract will extract all files to the current directory. If the specified directory does not exist, it will be created. How- ever, the parent directory must exist or extracting will fail. -P, --password PASSWORD Specifies the password to decrypt encrypted files. The password is assumed to be encoded as UTF-8 and converted the internal encoding according used in the installer as needed. Use the --password-file option to load the password from a file or standard input instead. This option cannot be combined with --pass- word-file. If this password does not match the checksum stored in the in- staller, encrypted files will be skipped but unencrypted files will still be extracted. Use the --check-password option to abort pro- cessing entirely if the password is incorrect. --password-file FILE Load a password form the specified file. Only the first line exclud- ing the terminating carriage return and/or line break is used as the password. The password is assumed to be encoded as UTF-8 and con- verted the internal encoding according used in the installer as needed. If the special file name "-" is used, the password will be read from standard input. Use the --password option to specify the password on the com- mand-line instead. This option cannot be combined with --password. If this password does not match the checksum stored in the in- staller, encrypted files will be skipped but unencrypted files will still be extracted. Use the --check-password option to abort pro- cessing entirely if the password is incorrect. -p, --progress[=ENABLE] By default innoextract will try to detect if the terminal supports shell escape codes and enable or disable progress bar output accord- ingly. Pass 1 or true to --progress to force progress bar output. Pass 0 or false to never show a progress bar. -q, --quiet Less verbose output. --show-password Show checksum $c and salt $s used for the password $p check as well as encoding of the password. The checksum is calculated from the salt concatenated with the password: $c = hash($s . $p) With the --silent option, the checksum name and hash is printed on one line separated by a space followed by the salt encoded as hex bytes and password encoding on separate lines. Checksum types can be CRC32, MD5 or SHA-1 although CRC32 is not used in installers with encryption. Use the --password or --password-file option together with --check-password to check if a password matches this checksum. -s, --silent Don't output anything except errors and warnings unless explicitly requested and use a machine-readable output format. This option can be combined with --list to print only the names of the contained files (one per line) without additional syntax that would make consumption by other scripts harder. -t, --test Test archive integrity but don't write any output files. This option can be combined with --extract to abort on file checksum errors. -T, --timestamps TZ Inno Setup installers can contain timestamps in both UTC and 'local' timezones. The --timestamps option specifies what timezone should be used to adjust these 'local' file times. Valid values are those accepted by tzset in the TZ environment vari- able, except with the direction of the time offset reversed: both -T CET and -T GMT+1 will (when DST is in effect) give the same result. Besides timezones, two special values are accepted: "none" Don't preserve file times for extracted files, both for UTC and 'local' timestamps. The file times will be left the way the OS set them when creating the output files. "local" Use the system timezone for 'local' timestamps. This is the normal Inno Setup behavior, and can be used together with the TZ environment variable. The default value for this option is UTC, causing innoextract to not adjust 'local' file times. File times marked as UTC in the Inno Setup file will never be adjusted no matter what --timestamps is set to. -v, --version Print the innoextract version number and supported Inno Setup ver- sions. If combined with the --silent option, only the version number is printed. Otherwise, the output will contain the name (innoextract) followed by the version number on the first line, and, unless the --quiet options is specified, the range of supported Inno Setup in- staller versions on the second line. --no-warn-unused By default, innoextract will print a warning if it encounters .bin files that look like they could be part of the setup but are not used. This option disables that warning. PATH CONSTANTS Paths in Inno Setup installers can contain constants (variable or code ref- erences) that are expanded at install time. innoextract expands all such constants to their name and replaces unsafe characters with $. For example {app} is expanded to app while {code:Example} is expanded to code$Example. There is currently no way to configure this expansion except for disabling it with the --dump option. EXIT VALUES 0 Success 1 Syntax or usage error 2+ Broken or unsupported setup file, or input/output error LIMITATIONS There is no support for extracting individual components and limited sup- port for filtering by name. Included scripts and checks are not executed. The mapping from Inno Setup constants like the application directory to subdirectories is hard-coded. Names for data slice/disk files in multi-file installers must follow the standard naming scheme.
