You want to rename all files removing the "-l"?

ie 

cindi_001-l.jpg to cindi_001.jpg
cindi_002-l.jpg to cindi_002.jpg

?

If you are talking about the "rename" command (came with Debian Perl) then what has 
worked for me is

~$ rename 's/old_file_regex/new_file_regex/' matching_file

So in the above example I would try

~$ rename 's/-l\.jpg/\.jpg/' *.jpg

    A simple one is the rename command which is included with the Debian perl
    package and almost certainly available to you already.

    The rename command allows you to rename files with full perl expressions,
    in a simple manner.

    For example our preceding example of changing the extension can be
    achieved with:

    skx@lappy:~$ rename 's/\.JPG/\.jpg/' *.JPG

    We can also, for example, strip spaces from filenames with this:

    skx@lappy:~$ rename 's/ //' *.JPG

    Renaming files from upper to lower case can be a simple job:

    skx@lappy:~$ rename 'y/A-Z/a-z/' *
