This is great. So now I've learned 2 new things about bash.

Do newer versions of bash accept statements in the form of
x`blahblah` != x ? I know you've said it works in older shells, but
it doesn't seem to work in mine. I don't know if I'm typing it wrong,
but I also tried `echo hi` at the command prompt and got the message
"bash: hi: command not found". Just wondering...

This is the first time I've seen the xargs command. It's quite handy!
