I wrote a small perl program to more quickly read all the subjects in an email list. One of the things the script does is to remove the mailing list name which repeats for every message and consists of a [, some English text and finally a ].
I was able to write a RE that identifies that text and cause the script to save that string in a variable called $remove. That part works and looks like: foreach my $field (@fields) { #Assemble the new subject. if($field =~ m/\[(.*?)\]/) { #$field is the blocked field. $remove = $field; } #field is the blocked field. else { #$field is not the blocked string. $newest = $newest . $field; } #$field is not the blocked string. } #Assemble the new subject. if ( $newest eq $previous ) { #Skip this iteration. $newest = ""; next; } #Skip this iteration. else { #they are different. This is where things don't quite work yet. At this point, I have $remove which contains that bracketted list name such as [BLIND-HAMS] or any number of other names enclosed in brackets. So, the next thing I do is to attempt to remove just that part of the subject line, keeping everything else that was there. $subject =~ s/'$remove'//; print( $subject, "\n" ); The example, here is the closest thing to anything happening. In the case of [BLIND-HAMS] the B is gone but the brackets and everything else remains I looked around for examples of similar code and found $subject =~ s/$remove\K.*?(?=\d+)//; It looks like it should keep everything else in the $subject string except [BLIND-HAMS] but it keeps everything including that so there is no change. I actually think I am close but the line with the brackets may be confusing the shell although single and double quotes don't make any difference. I also may have damaged that last example when I modified it to work with a string called $subject which is the whole subject line and $remove which is the part I am trying to remove. The rest of the script appears to work and is designed to only list the first message in a list of N messages of the same subject. so, if there are 120 messages with the subject of "how did you spend your Summer?", I read the first of those subject lines and none until the first message that doesn't have that title. Any constructive ideas are appreciated. Thank you.
