in reply to Need help for extracting Log file using Perl script

Assuming that there are no two equal lines in one file and files are not too big two simple loops will do the job:
#!/usr/bin/perl $fnx = "file1"; $fny = "file2"; $fnz = "file.uncommon"; $fntmp = "file.common"; open FPX, "$fnx" or die "Error in write:$!"; open FPY, "$fny" or die "Error in write:$!"; open FPZ, ">$fnz" or die "Error in write:$!"; open FPTMP, ">$fntmp" or die "Error in write:$!"; @x_lines = map {s/^\s+//; s/\s+$//; $_ } <FPX>; @y_lines = map {s/^\s+//; s/\s+$//; $_ } <FPY>; for $xnr(1..@x_lines) { $x = $x_lines[$xnr-1]; $matched = 0; for $ynr(1..@y_lines) { $y = $y_lines[$ynr-1]; if($x eq $y) { print "Saving matched at $xnr\n"; print FPTMP "$x \n"; $matched = 1; last; } } if(!$matched) { print "Saving unmatched at $xnr\n"; print FPZ "$x \n"; } } close FPX; close FPY; close FPZ;

[1nickt]: Corion I feel that way a lot when I look at the news...
[1nickt]: Brethren, I just noticed in the CPAN ticker Retry, which led me to Attempt, by Mark Fowler. Does anyone have experience with either of these utilities?
[Corion]: No. Back when I toyed with the idea, I found that writing the loop explicitly was usually less code than passing the configuration+ callback to the retrier...
