rename

Rename multiple files. Note: this page refers to the command from the rename Debian package. More information: https://manned.org/file-rename.

• Rename files using a Perl Common Regular Expression (substitute 'foo' with 'bar' wherever found):

rename {{'s/foo/bar/'}} {{*}}

• Dry-run - display which renames would occur without performing them:

rename -n {{'s/foo/bar/'}} {{*}}

• Force renaming even if the operation would remove existing destination files:

rename -f {{'s/foo/bar/'}} {{*}}

• Convert filenames to lower case (use -f in case-insensitive filesystems to prevent "already exists" errors):

rename 'y/A-Z/a-z/' {{*}}

• Replace whitespace with underscores:

rename 's/\s+/_/g' {{*}}
