remove certain part of file name

hey all :>
i have several files which start with an URL in the file name such as www.foo.net_01.foo.jpg.
how can i remove the url in the beginning that i have a clean filename (foo.jpg)?

after some googling i found out that it's possible with find and sed but i have no clue how to exactly strip the file name with sed

thanks in advance and best regards :>

prename 's/^www\..+_(.+)$/$1/g' *.jpg

It'll croak on www.foo.com_file_name.jpg (you should provide real input and expected output)

Re: remove certain part of file name

#!/bin/bash
for file in *
do
     newname1=${file##*_}
     newname2=${newname1#*.}
#  echo $file - $newname2
     mv $file $newname2
done

Untested, so recommend running with mv line commented and echo line uncommented first.

If you have files in the dir that do not fit the name format, you may want to put in an if statement to ignore those - I use =~ and a regular expression.

Keeping it around as a script is probably a good idea.

For a graphical method try using gprename, its in the repos.

Re: remove certain part of file name

rename www.foo.net_01. '' www.foo.net_01.*

works as well.

(obviously only if they all start with the same url)
