rename - renames multiple files
rename [ -h|-m ] [ -v ] [ -n ] [ -f ] [ -e perlexpr]*|perlexpr [ files ]
renamerenames 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
$_string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.
For example, to rename all files matching
*.bakto strip the extension, you might say
rename 's/\e.bak$//' *.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 rename.
- -f, -force
Over write: allow existing files to be over-written.
- -h, -help
Help: print SYNOPSIS and OPTIONS.
- -m, -man
Manual: print manual page.
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.
No environment variables are used.
If you give an invalid Perl expression you'll get a syntax error.
renamedid not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker).
