    how to say, zip code Starts With

    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...

    how to say, zip code Starts With

    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!

    understanding Hashes

    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.

    understanding Hashes

    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...

    break out STDIN into single letters

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

    break out STDIN into single letters

    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 ;-)

    break out STDIN into single letters

    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...

    break out STDIN into single letters

    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...

    pull only rows where field 2 is 'WI' in tab-delimited file

    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.

    pull only rows where field 2 is 'WI' in tab-delimited file

    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...

    Putting "awk" inside of perl, system `cmd`

    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...

    Putting "awk" inside of perl, system `cmd`

    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...

    load a System command into a Variable

    Thank you kevin! That makes perfect sense. I see it now. do you know why this: my $proc = `ps -ef | grep java3 | egrep -v grep | awk '{print $2}'`; print $proc; gives me the entire process information instead of JUST the process id?

    load a System command into a Variable

    Hi columb, well, to be honest - the main reason is because I'm very much new to this - and really only know one way of doing it. I looked in my perl book for PIPE - and it's not in there. (It's the O'Reilly Learning Perl book). Is that more of an advanced function? Also, a question - this isn't...

    load a System command into a Variable

    cool. thx for the help - there *should* be only 1 process id that is returned. I tried to really narrow it down by grepping 'java3' - which is VERY specific to this one process and no other running process should have this in its command. Also, the egrep -v should get rid of the grep pid. So...

    load a System command into a Variable

    hello, i would like to load a system command into a variable. The system command is: system "ps -ef | grep java3 | egrep -v grep | awk '{print $2}'"; I'm guessing the way I would do this is: my $proc = system "ps -ef | grep java3 | egrep -v grep | awk '{print $2}'"; But i have a question...

    incorrect Results - Looping through Files & substr ()

    KevinADC, OK that worked like a charm. Wow. I'm impressed. i'm not totally sure how that was constructed or how you knew to do it that way - but I am studying it, to see if I can make more sense of it. Here's another little complication, what if I want it to be like - in the housenumber range...
