Top Forums UNIX for Dummies Questions & Answers How to parameterize multiple search patterns and generate a new file Post 38868 by augustinep on Tuesday 29th of July 2003 10:53:54 AM

Thanks Perderabo. Just two clarifications.


One:

Since we have given

grep "\*100.*\*-" < test > test2

the output file could also contain lines like these:

123*1000*ade*-15
123*100.00*abc*-10
123*100*ade*-20
123*100.*ade*-15

How will I restrict it to only "*100*". i.e., only the third line from above should be returned as it contains an exact string of "*100*" and "*-" ?

Two:

Is it possible to parameterize these patterns("*100*" and "*-" and so on) into a file that could be used in the search?

NAME
IO::Digest - Calculate digests while reading or writing SYNOPSIS
use IO::Digest; # Get a Digest::MD5 object that takes input while $fh being written or read my $fh; my $iod = IO::Digest->new ($fh, 'MD5'); print $fh "fooo"; print $iod->hexdigest DESCRIPTION
This module allows you to calculate digests while reading or writing file handles. This avoids the case you need to reread the same content to compute the digests after written a file. TEST COVERAGE
