rename - renames multiple files
] [ -n
] [ -f
"rename" renames the filenames supplied according to the rule
specified as the first argument. The perlexpr
argument is a Perl
expression which is expected to modify the $_ string in Perl for at least some
of the filenames specified. If a given filename is not modified by the
expression, it will not be renamed. If no filenames are given on the command
line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the
extension, you might say
rename 's/\e.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
- -v, -verbose
- Verbose: print names of files successfully renamed.
- -n, -nono
- No action: print names of files to be renamed, but don't
- -f, -force
- Over write: allow existing files to be over-written.
- -h, -help
- Help: print SYNOPSIS and OPTIONS.
- -m, -man
- Manual: print manual page.
- -V, -version
- Version: show version number.
- Expression: code to act on files name.
May be repeated to build up code (like "perl -e"). If no
-e, the first argument is used as code.
- Statement: code to act on files name, as -e but
terminated by ';'.
No environment variables are used.
If you give an invalid Perl expression you'll get a syntax error.
The original "rename" did not check for the existence of target
filenames, so had to be used with care. I hope I've fixed that (Robin
