One liner for renaming files

[D. Alvarado]

Hello,
I am looking for a one line command that I could run with perl to
rename a group of files. The desired outcome is

start end
----- ---
ctf_005.liv ctf05cae002.liv
ctf_006.liv ctf05cae003.liv
ctf_007.liv ctf05cae004.liv
ctf_008.liv ctf05cae005.liv

and so on.

Any advice is greatly appreciated, - Dave

I am looking for a one line command

Why restrict it to one line?

If someone has a two-line solution, they should not post it?

and so on.

Get it working with many lines of code first, then pare it
down to one line. Post here if you get struck.

An example is not a specification. It would be helpful if you
described what transformation you want to have made...

perl -e 'for (@ARGV){($to=$_)=~s/_(\d+)/sprintf "05cae%03d",$1-3/e; \
rename $_,$to or warn $!}' ctf_*.liv

People can go mad on the golf course though so you might want to
create a more general utility and save it to a file. There are
simply too many things that go wrong with one-liners unless they're
simple.

hth,

Following would be overkill many times over for you then...
