( #3333=superdoc: print w/replies, xml ) Need Help??

Thank you in advance for answering my question, I have been searching all afternoon for the correct regex to use and I feel the need to elevate the issue.

I am searching through a series of files, the beginning of the filename is guaranteed to have the first 6 characters as A-Z, the next two characters will be any combo of A-Z,0-9. The following two characters are A-Z. It is these last two characters that I am trying to match. I am running into problems where I am matching characters accidentally from the first part of the filename. E.g. If if I were searching for TL, STTLWA02TL01_2011-10- would correctly match, STTLWA02HJ01_2011-10- would erroneously match.

So my question is: how can I match my desired characters after the 8 initial characters?

This regex is obviously insufficient, since if $prompt_host = "TL", it will match it anywhere in the filename.

#Populate @traffic_file_list while (my $file = readdir(DIR)) { if($file =~ $prompt_host) { push(@traffic_file_list, $file); } }

Thank you!

  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
