[Linux-ham] linux script thing -- not doing WGET. I'm missing something

I've found that when a script runs as a process you need to put the full
path to the file you want to manipulate. Even if you specify the paths, for
some reason the automated processes will not respect it. The confusing
thing is, if you run the script as root it works fine. It only fails when
its run via an automated process. Example : rm textfile.txt will fail.
But, rm /home/myuser/textfile.txt will work. The no such file output
generally is an indication of this. This might not be all that is tripping
you up, but might help on the file not founds.
