FOLLOWUP: grep

A small P.S. to the summary for grep, and apologies for the bandwidth
used......

It began to bug me - imagine if the desired character was byte 73....! :-)
So after a long while (I wonder how I can explain what I was doing
half the afternoon!) I came up with:

grep A3L0 trash.old | grep '^.\{21\}7'

It's only a few characters shorted, and a lot less simple. But it might
be useful if the character being sought is near the end of the input line.

You should see the files I generated to test this, and the .history file
of my numerous "grep" attempts!!! Anyway, sorry for flogging the
proverbial dead horse. On with your regularly scheduled mailing list.
