Thank you much for the tips! This worked great. So, once again coming from the SQL point of view - what if i have SEVERAL zip codes that i'm looking for? what if i want to say, If $ZipPlus4 has a value in ('29626', '29627', '29628', '29788') then increment $n += 1, and if it's NOT in those...

hello, I am more of an SQL person - so what I am trying to say, I am not sure how to say in Perl. I am sure it is some sort of regular expression. Maybe YOU can help me! I would like to say, if ($ZipPlus4 STARTS WITH 29626) then increment n. any hints? thank you!

thank you Ishnid :-) very helpful and useful.

thank you for the info! another question - do you find that you use Hashes often in your perl programming? I am understanding the concept as it's presented in the book - but not sure how i will apply it in-real-life.

Hello! I am new to Perl and have been using it intermittently in a QA role. Mainly for parsing & testing tab delimited files. I am reading through the Learning Perl book & working through Chapter 5 right now which is a chapter on hashes. I am not sure I'm understanding a Hash on the large...

nice! thanks rharsh for the tip! any thoughts on how to break it up into groups of 5, putting a space in-between?

i just tried Cygwin, but i still can't copy and paste from the screen ... whats up with that?

HEY! can i ask another question? So i wrote out an decoder and an encoder. But with the encoder - i want the blocks to be spaced in groups of 5. So if i wanted to say "I wrote a perl to encode and decode" - the program would return this to me: KN4H5 CQ9C4 S5HCO 8HFCQ OFFC8 HFC instead of this...

holy crap! that *IS* simple :-) thanks Trojan and sorry for the scare ;-)

Hello! thank you so much for the valuable input. Forgive the slowness of my brain - this is not something I particularly EXCEL at (at least not yet - let's hope that changes). I *would* use the "tr" option - but it's only mentioned very briefly in 'Learning Perl' and I'm not sure I can really...

Hello, I am new to perl and working my way through the Learning Perl book. I'm only on page 37, so bear with me!!! I want to take STDIN and break it into letters. It's a decoder program. Like, for example, if someone types in: LC8Q4 CBDSN XQRHD NKJXB HR into STDIN ... it will come out as BECAR...

I bet it is very similar to what was posted for kre1973 ... except that I need the "WI" or "OR" or "NE" or whatever state I need to occur in field 2 - instead of, say, the last name field or something.

hello! I have a story problem for you. I have a tab-delimited file. The 2nd field is the "state" field, and I want to pull out of this file, and write to a NEW file, only the rows that have Wisconsin as their state. 'WI' I believe I need to use "split" but not sure how. This is how far I've...

Thank you! Yes, I had posted something very similar & was still not able to do what I wanted, but this time I *believe* i've got it. I needed to "split", which I wasn't doing - so thank you for that hint. system "rm seq2"; $ps=`ps -ef | grep java`; print "$ps"; @pid=split /\s+/, "$ps"; print...

hello, does perl allow/understand when i use AWK inside of a system command? I can't understand why this isn't working: $pid=`ps -ef | grep java | egrep -v grep | awk '{print $2}'`; print "$pid"; when i type: ps -ef | grep java | egrep -v grep | awk '{print $2}' at the command prompt itself...
