[plug] Small problem with cut

[J Michael Gilks]

Rather than just sending out a reply, I have now tested using cut and 
discovered th problem.
The output going to cut is not tab delimited but uses spaces.
On your system
ps aux | grep "kdeinit: konqueror -session" | cut -f 6 -d " "
should give the result you are after. Still very dependent on size of names 
etc.
Got it. Need to convert space to tabs, use perl
ps aux|grep "kdeinit: konqueror -session"|perl -p -e 's/\s+/\t/g' - | cut -f2
Little perl bit converts one or more spaces to a tab, therefore fields are 
where they should be. This has been fun, hope it has helped.

Love
Mike.
