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
