you are correct. i may have made the mistake of testing on two different
files. one called "a" in my Xterm and one called ".profile" in my vty.
the "expr" came up empty with "a", but not with ".profile", which caused
the error. i also may have missed it because the vty is faster than my
Xterm (i was using the code to load an application, so i could only see
the error briefly). thanks.
hopefully someday i'll get the hang of this!
btw = this code strips prefixes ( equal to ${j##*.} ).
