Arthur Bols 89c43ca8e4 rename: address different versions of the command (#3126) 
Address the presence of multiple and different versions of the rename command
as discussed in issue #3125.

Changes made:

- Moved common/rename.md to linux/prename.md, documenting the Debian
  Perl rename command (which is deprecated).
- Created linux/file-rename.md for the Debian/Ubuntu `file-rename`.
- Created linux/perl-rename.md with examples for Arch Linux `perl-rename`.
- Created linux/rename.md for the `rename` command offered by the the
  `util-linux` package, the most common one and supported by the most
  platforms.

rename

Rename multiple files. NOTE: this page refers to the command from the perl-rename Arch Linux package.

  • 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' {{*}}
