CentOS 7 specifies `man rename` : rename [options] expression replacement file... The rename example fails with "rename: not enough arguments".

  Unfortunately, there are two incompatible rename programs in the wild. :( Debian ships this: https://metacpan.org/pod/distribution/File-Rename/rename.PL https://metacpan.org/pod/distribution/File-Rename/rename.PL Most(?) other distros ship the one from util-linux: http://man7.org/linux/man-pages/man1/rename.1.html http://man7.org/linux/man-pages/man1/rename.1.html

  Don't read it like this: rename <expression> <replacement file> ... Read it like this: rename <expression> <replacement> <file(s)...> Argument 1 is a string (not a regex), argument 2 is string to replace the old string, and arguments 3+ is a file, or list of files, or a glob. The man page includes a warning about the lack of safeguards. It is unfortunate that rename doesn't have an equivalent of mv or cp's -i flag because it's so easy to overwrite files if your expressions aren't exactly correct. On some Ubuntu systems, I've seen another version of rename that's actually a Perl script that uses regular expressions. I think that version lets you set some safeguards, which are sorely lacking in the binary version of rename that ships with CentOS.

  It's available in Fedora under the name "prename". I've asked the maintener to make it available for EPEL 7, will this work for you?
