rename - renames multiple files
rename [ -h|-m|-V ] [ -v ] [ -0 ] [ -n ] [ -f ] [ -e|-E perlexpr]*|perlexpr [ files ]
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
$_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.
For example, to rename all files matching
*.bak to strip the extension, you might say
rename 's/\.bak$//' *.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.
- -0, -null
Use \0 as record separator when reading from STDIN.
- -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.
- -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.
rename did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker).
