The zd-mtx excitement continues...
I found that the script was getting confused when I had an amlabel which
was a substring of another amlabel. i.e. "Kiva2" and "Kiva22". When the
script grepped the amlabel out of the labelfile it was matching more than
one line.
My solution is just to use "grep -w" instead of "grep" in the appropriate
places. (In GNU grep the -w flag is "Select only those lines containing
matches that form whole words.")
My question is, does anyone have a grep in which the -w flag is
nonexistent or means something different? In which case the answer might
have to be "get GNU tools" because I can't think of any other solution I
really like. I can think of a couple but they're all gross hacks.
A "diff -uNr" is below.
Thanks,
