FDUPES(1) General Commands Manual FDUPES(1) NAME fdupes - finds duplicate files in a given set of directories SYNOPSIS fdupes [ options ] DIRECTORY ... DESCRIPTION Searches the given path for duplicate files. Such files are found by com- paring file sizes and MD5 signatures, followed by a byte-by-byte compari- son. OPTIONS -r --recurse For every directory given follow subdirectories encountered within. -R --recurse: For each directory given after this option follow subdirectories en- countered within (note the ':' at the end of option; see the Exam- ples section below for further explanation). -s --symlinks Follow symlinked directories. -H --hardlinks Normally, when two or more files point to the same disk area they are treated as non-duplicates; this option will change this behav- ior. -G --minsize=SIZE Consider only files greater than or equal to SIZE in bytes. -L --maxsize=SIZE Consider only files less than or equal to SIZE in bytes. -c --cache Speed up file comparisons by keeping track of their signatures in a database; additional parameters may be provided using one or more cache parameters (as indicated below). Please note that this option may not be available on some systems. -x cache.OPTION Supply an optional cache parameter, where OPTION is one of the key- words below and multiple options may be supplied via successive -x arguments: readonly read but do not update file signatures prune look through entire cache and delete orphaned entries clear clear all entries from cache vacuum reduce size of DB file, if possible The options prune, clear, and vacuum may be employed without supply- ing a DIRECTORY argument, and will take effect even if readonly is also specified. The order of operations is always clear, prune, up- date signatures (unless readonly), and vacuum. -n --noempty Exclude zero-length files from consideration. -A --nohidden Exclude hidden files from consideration. -f --omitfirst Omit the first file in each set of matches. -1 --sameline List each set of matches on a single line. -S --size Show size of duplicate files. -t --time Show modification time of duplicate files. -m --summarize Summarize duplicate file information. -M --quicksummary Summarize dupe information quickly, skipping the slower byte-for- byte match confirmation. -q --quiet Hide progress indicator. -d --delete Prompt user for files to preserve, deleting all others (see CAVEATS below). -D --deferconfirmation In interactive mode, defer byte-for-byte confirmation of duplicates until just before file deletion. -P --plain With --delete, use a line-based prompt (as with older versions of fdupes) instead of the new screen-mode interface. On installations where the screen-mode interface is not supported, fdupes will de- fault to a line-based prompt. -N --noprompt When used together with --delete, preserve the first file in each set of duplicates and delete the others without prompting the user. -I --immediate Delete duplicates as they are encountered, without grouping into sets; implies --noprompt. -p --permissions Don't consider files with different owner/group or permission bits as duplicates. -o --order=WORD Order files according to WORD: time - sort by modification time, ctime - sort by status change time, name - sort by filename. -i --reverse Reverse order while sorting. -l --log=LOGFILE Log file deletion choices to LOGFILE. -v --version Display fdupes version. -h --help Display help. NOTES Unless -1 or --sameline is specified, duplicate files are listed together in groups, each file displayed on a separate line. The groups are then sep- arated from each other by blank lines. When -1 or --sameline is specified, spaces and backslash characters (\) appearing in a filename are preceded by a backslash character. EXAMPLES fdupes a --recurse: b Will follow subdirectories under b, but not those under a. fdupes a --recurse b Will follow subdirectories under both a and b. CAVEATS When using -d or --delete, care should be taken to insure against acciden- tal data loss. When used together with options -s or --symlink, a user could accidentally preserve a symlink while deleting the file it points to. Furthermore, when specifying a particular directory more than once, all files within that directory will be listed as their own duplicates, leading to data loss should a user preserve a file without its "duplicate" (the file itself!).
