removing white space (padding) from variables?
I stored results like this

VAR=`wc -l < ls.txt`

But the value of the wc gave me a padded number.
How do I strip the padding from $VAR?

Do you think I could use SED?
Except instead of a file input, have a variable redirection input?

Good idea, I'm kind of a forum newbie, I didn't know forums have search functions. I'll try that next time before posting any questions.
