sccs-unget(1) User Commands sccs-unget(1) NAME sccs-unget, unget - undo a previous get of an SCCS file SYNOPSIS /usr/ccs/bin/unget [-ns] [-q[nsedelim]] [-rsid] [-Nbulk-spec] s.filename... DESCRIPTION The unget utility undoes the effect of a get -e command executed before the creation of the pending delta. If a directory name is used in place of the s.filename argument, the unget command applies to all s.files in that directory. Unreadable s.files pro- duce an error; processing continues with the next file (if any). The use of `-' as the s.filename argument indicates that the names of files are to be read from the standard input, one s.file per line. OPTIONS The following options are supported: -n Retains the retrieved version, which is otherwise removed. -s Suppress display of the SCCS delta ID (SID). -rsid When multiple versions are checked out, this option specifies which pending delta to abort. A diagnostic results if the specified SID is ambiguous, or if it is necessary but omitted from the command line. -q[nsedelim] Enable NSE mode. If NSE mode is enabled, several NSE related exten- sions may be used. In this release, the value of nsedelim is ig- nored. This option is an undocumented SUN extension that does not exist in historic sccs implementations. -Nbulk-spec Processes a bulk of SCCS history files. This option allows one to do an efficient mass processing of SCCS history files. The bulk-spec parameter is composed from an optional list of flag parameters followed by an optional path specifier. The following flag types are supported: ++ If bulk-spec is preceded by a `++', unget(1) expects to process filenames that are prepended by a plus sign, the related SID and another plus sign following the form: +sid+filename This permits each file to be retrieved with an individual SID. space This is a placeholder dummy flag that allows one to use a prepared string for the -N option and to replace the space character by one of the supported flags on demand. The following path specifier types are supported: -N The file name parameters to the unget command are not s.filename files but the names of the g-files. The s.filename names are automatically derived from the g-file names by prepending s. to the last path name component. Both, s.filename and the g-file are in the same directory. -Ns. The file name parameters to the unget command are s.file- name files. The the g-files names are automatically de- rived by removing s. from the beginning of last path name component of the s.filename. Both, s.filename and the g- file are in the same directory. -Ndir The file name parameters to the unget command are not s.filename files but the names of the g-files. The s.filename names are put into directory dir, the names are automatically derived from the g-file names by prepending dir/s. to the last path name component. -Ndir/s. The file name parameters to the unget command are s.file- name files in directory dir. The the g-files names are automatically derived by removing dir/s. from the begin- ning of last path name component of the s.filename. A typical value for dir is SCCS. In order to overcome the limited number of exec(2) arguments, it is recommended to use `-' as the file name parameter for unget(1) and to send a list of path names to stdin. This option is a SCHILY extension that does not exist in historic sccs implementations. -Xextended-options Specify extended options. The argument extended-options may be a comma separated list of extended option names. The following extended options are supported, they may be abbrevi- ated as long ad the abbreviation is still unique. Options with para- meter may not be abbreviated. 0 When reading filenames from stdin, triggered by a file name argument `-', the filename separator is a null byte instead of a newline. This allows one to use long lists with arbi- trary filenames. help Print a short online help for available options. The -X option is a SCHILY extension that does not exist in historic sccs implementations. -V -version --version Prints the unget version number string and exists. This option is a SCHILY extension that does not exist in historic sccs implementations. ENVIRONMENT VARIABLES See environ(7) for descriptions of the following environment variables that affect the execution of unget(1): LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH. SCCS_NO_HELP If set, unget(1) will not automatically call help(1) with the SCCS error code in order to print a more helpful error message. Scripts that depend on the exact error messages of SCCS commands should set the environment variable SCCS_NO_HELP and set LC_ALL=C. EXIT STATUS The following exit values are returned: 0 Successful completion. 1 An error occurred. FILES p.file permissions (lock) file for checked-out versions. See sccs-get(1) for a description of the layout of the p.file. q.file temporary copy of the p.file; renamed to the p.file after completion z.file temporary lock file contains the binary process id in host byte or- der followed by the host name dump.core If the file dump.core exists in the current directory and a fatal signal is received, a coredump is initiated via abort(3).

Rochkind at Bell Labs in 1972. Release 4.0 of SCCS, introducing new versions of the programs ad- min(1), get(1), prt(1), and delta(1) was published on February 18, 1977; it introduced the new text based SCCS v4 history file format (previous SCCS releases used a binary history file format). The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite has been maintained by Joerg Schilling and the schilytools project authors.
