Power Perl removing all strings but the final few characters from a variable value

Dear all,

I have a variable called $abc, which the value is something like below,

*** *********** : *****

where * can be anything. I need to remove all but the final characters until last whitespace.

example

grd groupstudy : tutor6/7

becomes tutor6/7

something like
Code:
if $myvalue=1 {

modify $abc as mentioned above and the new value becomes $myvalue2.
$abc value remains unchanged.

}

thank you for your kind help!. Smilie

UPDATE-METAINIT(1)					User Contributed Perl Documentation					UPDATE-METAINIT(1)

NAME
update-metainit - Generates init scripts SYNOPSIS
update-metainit [--remove initname [--purge] ] DESCRIPTION
Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis- trator. If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment. OPTIONS
--remove initname This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname. --purge Only usable with --remove. Will remove the generated files even if modified. SEE ALSO
