CHGREP(1)CHGREP(1)NAMEchgrep - change oldpattern to newpattern
SYNOPSISchgrep [-en/w] [-dhilqrsv] [-t filename] OLDPATTERN NEWPATTERN
[file...]
DESCRIPTION
Chgrep searches the input files (or standard input if no files are
named) for oldstring and changes them to newstring. If some file and
file.lock exist then chgrep leaves both files unchanged. You can write
NEWPATTERN as "NULL" to clear OLDPATTERN, i.e. "chgrep oldstring NULL
somefile.c".
-d Don't change modification times of altered files.
-e Extended-regexp.
-h Print the version number of chgrep to standard output. This
version number should be included in all bug reports (see
below).
-i Ignore differences in case at OLDPATTERN.
-l Leaves copy of old file unchanged in filename.lock
-n Treat <newline> as a regular character.
-q Quiet mode (no output at all).
-r Read all files under each subdirectory, recursively.
-s Simulation mode.
-t Use not default file.lock for caching.
-v Prints to standard output diagnostic informations.
-w Doesn't recognize regexp in OLDPATTERN. This option accelerates
the whole process. Incompatible with -e and/or -n.
DIAGNOSTICS
Normally, exit status is 0 if no errors were found, and 1 if some
errors were found. The -v option helps to understand the sense of the
exit status.
BUGS
Email bug reports to bartek@bmk.bz. Be sure to include the word
“chgrep” somewhere in the “Subject:” field.
