RREP

NAME

rrep − replace patterns in files.

SYNOPSIS

rrep [OPTIONS] PATTERN REPLACEMENT [FILE...]

DESCRIPTION

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.

OPTIONS

−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 descibes 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

Exit status is 1 if any error occurs, 0 otherwise.
