Sometimes It’s necessary to rename files following some patterns. Do this task manual is a long task, if you thousand of files. For this reason, I use rename command:
Debug and preview:
$ rename’REGULAR EXPRESSION’ files -n
$ rename’REGULAR EXPRESSION’ files
Some of the most common expressions I use are:
Convert filename to lowercase:
$rename ‘y/A-Z/a-z/’ *
Add Prefix to filename:
$rename ‘s//text-/’ *.mp3
$rename ‘s/ – text//’ *.mp3
rename ‘s/(.*?)-(.*).mp3/$2-$1.mp3/’ *.mp3
More Information in manual of rename:
rename – renames multiple files
rename [ -v ] [ -n ] [ -f ] 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/’ *
Verbose: print names of files successfully renamed.
No Action: show what files would have been renamed.
Force: overwrite existing files.
