<p dir="ltr">Yay! Nice work. Xargs is a very useful tool and you've hit some really salient points of usage.</p>
<p dir="ltr">I use xargs almost daily for removing unneeded packages using yum. Rpm -qa |grep offendingpackage | xargs yum remove. That runs once and fails as I didn't hit OK. That allows me to see what else will be removed with offendingpackage. Once I'm ok with the remivak, I run it again and make it yum -y remove.</p>

xargs is a gender-changer type program that adapts one program's stdout<br>
to the next program's command line arguments. It's extremely handy for<br>
shell scripting, but it can be tricky. I've written a short guide for<br>
xargs that shows how to get around the usual xargs landmines:<br>
