in reply to regex alternation

at first it will be a bit faster if you dont use an alias for $_. perhaps try map to increase the speed.. im intrested too in this case.. probably there is a solution via hashing.. u need exactly match||no match prints? or you "only" need the matched lines? <= if so it can be done faster 4 sure..
for(@test_array){print "MATCHED\n" if $_ =~ $test3 && next; print "NO MATCH\n";} #untested
futhermore check:
How do I optimize a regular expression? and
Perl regexp matching is slow??

$perlig =~ s/pec/cep/g if 'errors expected';

[ambrus]: Corion: sure, this is the long-term plan. The short term is that I have to run this ungodly mess to get results from the new input data today.
[Corion]: ambrus: Most of our "automation" is tied to process exit codes and a shell pipeline :-\
[LanX]: ... a week later they realized that one of the databases - which recorded how much the other banks due to this bank - was not correctly plugged
[ambrus]: Corion: I have no problem with exit codes and shell pipeline. My problem is that the current process requires a lot of manual intervention from me, including editing the source codes.
[ambrus]: (Also a lot of manual intervention by two or three other co-workers, who do other parts of the process.)
[ambrus]: Some of the manual part is unavoidable, but not all.
[choroba]: LanX was there a way to recover the numbers from the remaining information?
[Corion]: LanX: Ow ;)
