Shell Programming and Scripting

I am special requirements to rename file.

I have files with names like below:

1_firstname1_lastname1.html
2_firstname2_lastname2.html
3_fistname3_lastname2.html

I would like these file to be renamed as below

firstname1_lastname1.html
firstname2_lastname2.html
fistname3_lastname2.html

I would like to rename files by removing text before the first occurrence of ‘_' and ‘_'.

Is there any way with sed or awk to achieve this?

This is pretty easy one:

Code:

#!/usr/bin
for file in *_*
do
        r_name=${file#*_}
        mv $file $r_name
done

If you have the rename command, then the following is one of the easiest way of doing things.,

Code:

rename 's/\d_//' *.html

Code:

$ ls
1_firstname1_lastname1.html  2_firstname2_lastname2.html  3_fistname3_lastname2.html
$ rename 's/\d_//' *.html
$ ls
firstname1_lastname1.html  firstname2_lastname2.html  fistname3_lastname2.html

This code, some how not working for me. File names are no changed. they remain same.
I have rename on my Linux and used /bin/bash as defualt shell

how about this ?

Code:

rename 's/[0-9]_//' *.html

To remove anything before the first _

Code:

rename 's/^[^_]*_//' *_*.html

But I would use freelong's for loop example..
