Thanks! Finally got the right search term. After a little more searching, fyi for posterity, i set the variables with:
DIR=`dirname $1`
INPUT=`basename $1`
I was having problems before too because I didn't realize that there could be no spaces when setting variables!
Works now, thanks again.
EDIT: Not working... sort of pissing me off. I did this the first time, and it returned the dirname and basename of the file the script was running on with $1, but now it won't anymore. dirname is empty and it just returns "usage:dirname path"
EDIT: And it works again...I realized that getting the dirname from $1 or $0 the way I am doing it gets problems if any of the folders in the path have spaces in them because i assume that it takes the space for a new "field"... Might be using improper terminology, but $1 might become $2 for example. My solution was to remove spaces from folder names... Anyone know how to do this otherwise so that there won't be a problem?
