pattern matching rename...

[bruce]

thanks todd...

at the risk of asking a rather basic question.. can someone explain exactly
what/why this seesm to work..

per your reply, i have :

 abcCAT.py
 abcCAT.txt

 i'd like to rename the files, so i get
 abcCAT_dog.py
 abcCAT_dog.txt

 i've been trying to figure out how to achieve what i want using
 rename and pattern matching.. i'm missing something.. and it's
 simple!!

 any thoughts/pointers?
$ rename . _dog. abcCAT.*
 ls abcCAT*
abcCAT_dog.py  abcCAT_dog.txt

this works. but i can't find any docs that give a good explanation of
how/why this works.

it appears that the rename is taking the "_dog" and adding it to the
"abcCAT"... but how would i know that this is going to occur.. is this
really what's going on.. what if i wanted to have the "_dog" added before
the abcCAT...

in searching the net (google) couldn't really find any good docs for this..

i was also under the impression that 'rename' could use regex's but i can't
figure out how..

thanks

$ rename . _dog. abcCAT.*
$ ls abcCAT*
abcCAT_dog.py  abcCAT_dog.txt

Beware that there are different programs named rename on different
distros.
