TLDR
Enter a command. For example: pacman key, sysctl, vmstat, lxc profile.

rename

 
Rename multiple files. NOTE: this page refers to the command from the prename Fedora package. More information: https://manned.org/man/prename.
 
  • 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' {{*}}
