Comments on Linux rename Command Tutorial for Beginners (with Examples)
If you work with files on the command line in Linux, renaming files is one of the most frequent tasks you may find yourself involved in. We've already discussed the mv command that lets you do this. And here, in this tutorial, we will discuss another such tool, dubbed rename.

rename is a tiny perl script. The pattern matching languague used is perl's regex engine which is extremely powerful. It can be used to act on hundreds of files with a single command, thanks to shell expansion.
Very powerful in the hands of a perl expert.
There are two different versions of the “rename” command (i.e., two *different* commands named “rename”) and you’re confusing them. The util-linux version takes arguments “expression” and “replacement”. You start out describing that, but then you give examples for the Perl version, which takes (only) a “perlexpr” argument.

Thanks,
but it's so poor your examples list
rename has two versions. Your detail is invalid.
