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.
