rename

Rename multiple files. NOTE: this page refers to the command from the util-linux package. For the Perl version, see file-rename or perl-rename. Warning: This command has no safeguards and will overwrite files without prompting. More information: https://manned.org/rename.

• Rename files using simple substitutions (substitute 'foo' with 'bar' wherever found):
  rename {{foo}} {{bar}} {{*}}
• Dry-run - display which renames would occur without performing them:
  rename -vn {{foo}} {{bar}} {{*}}
• Do not overwrite existing files:
  rename -o {{foo}} {{bar}} {{*}}
• Change file extensions:
  rename {{.ext}} {{.bak}} {{*.ext}}
• Prepend "foo" to all filenames in the current directory:
  rename {{''}} {{'foo'}} {{*}}
• Rename a group of increasingly numbered files zero-padding the numbers up to 3 digits:
  rename {{foo}} {{foo00}} {{foo?}} && rename {{foo}} {{foo0}} {{foo??}}
