I've written a small utility to be able to run egrep on a UD file (not
UD directory), however its implementation is not ideal.
Essentially, I select the file I'm searching, writing each record one at
a time to a temp UNIX file and running egrep on it as follows
!egrep -q -f MyTempRegexFile MyTempRecordFile ; echo $?
Where MyTempRegexFile is a file containing the desired regex pattern
stored earlier and MyTempRecordFile is a file name unique to each user.
My problem with it is that I have to do a READ on each record, followed
by a WRITE then have egrep read it in as well. That's a lot of seemingly
unneeded disk IO if I could only stream the record to egrep without have
to do a WRITE after the READ.
Any ideas? I feel I'm missing something quite obvious.
Regards,
Dan
