rrep - replace patterns in files.
rrep [OPTIONS] PATTERN REPLACEMENT
[FILE...]
The rrep utility searches input FILEs for matches to
a given PATTERN and replaces those matches by a given
REPLACEMENT. The pattern is, by default, a basic regular expression.
The replacement string may contain special characters to refer to portions
of the matched pattern.
Binary files are, by default, ignored. A file is regarded as
binary if it contains the null character.
- -E,
--extended-regexp
- PATTERN is interpreted as an extended regular expression
(ERE).
- -F,
--fixed-strings
- PATTERN and REPLACEMENT are interpreted as fixed strings,
not as regular expressions or escape sequences.
- -R, -r,
--recursive
- Each directory that is given on the command line is processed recursively.
Files and sub-directories starting with the . character are, by
default, ignored.
- --include=FILE_PATTERN
- Only files are processed that match the pattern FILE_PATTERN,
except for files that are specifically given on the command line.
*, ?, and [...] can be used as wildcards in
FILE_PATTERN. Wildcards and backslash characters can be quoted with
\.
- --exclude=FILE_PATTERN
- Files that match the pattern FILE_PATTERN will be skipped, except
for files that are specifically given on the command line (using wildcard
matching as described under --include).
- --exclude-dir=PATTERN
- Directories that match PATTERN will be skipped, except for files
that are specifically given on the command line (using wildcard matching
as described under --include).
- -V, --version
- Print the version number of rrep.
- -S SUFFIX,
--suffix=SUFFIX
- Override default backup suffix. This option implicitly activates
backups.
- -a, --all
- Files and sub-directories starting with the . character in
recursively processed directories (see --recursive) are processed
as well.
- -b
- Backup before overwriting files. The backup files are written into the
directory of the original file. Equivalent to using
--backup=existing.
- --backup[=CONTROL]
- Like -b but accepts a version control argument. The file name of
the backup file is appended by a ~ character. The backup suffix is
~, unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option
or through the VERSION_CONTROL environment variable. Here are the
values:
none, off never make backups
(even if --backup is given)
numbered, t make numbered backups
existing, nil numbered if numbered backups exist, simple
otherwise
simple, never always make simple backups
- --binary
- Do not ignore binary files. A file is regarded as binary if it contains
the null character \0.
- --dry-run
- The replacement is just simulated. No file is actually modified.
- -e PATTERN,
--regexp=PATTERN
- Use PATTERN for matching. This option can be used to specify a
pattern beginning with -.
- -h, --help
- Display a help message that describes the command line options and exit
afterwards.
- -i,
--ignore-case
- Case distinctions in PATTERN are ignored.
- --keep-times
- The original access and modification times of files and directories are
restored after processing.
- -p REPLACEMENT,
--replace-with=REPLACEMENT
- Use REPLACEMENT for substitution.
- --interactive
- Each time before a file is modified the user is prompted and can cancel
the modification.
- -q, --quiet,
--silent
- All normal output messages are suppressed.
- -s,
--no-messages
- All error messages are suppressed.
- -w,
--word-regexp
- Only those matches of PATTERN are replaced that match whole
words.
- -x,
--line-regexp
- Only those matches of PATTERN are replaced that match whole
lines.
Exit status is 1 if any error occurs, 0 otherwise.
