Re: head as in "unix"

You could write your own function that is a for loop that counts until 100, putting each line into the array and quits would work. There may be a more elegant way, though... Matt On Wed, 2002-09-18 at 09:31, Jakob Kofoed wrote: > > Hi there, > > Does Perl have a function like the UNIX head.

Preferred way to move and compress a file

I need to move several files and compress them - what's the preferred way to do this? I don't think Zlib::Compress is what I want, it seems more geared towards dealing with small streams... although I suppose I could look over each line and write that out. The files to compress are all several h

Parse data file

I need to get 2 fields out of a file which has the following format: #FIELD [tab]NAME=name to put into hash[newline] [tab]DATALINE=value to put with data[newline] [tab]EXTRA=several fields to ignore... [NEWLINE] #NEXTFIELD [tab]NAME ... I have thought of a couple ways I *could* do it, but I th

query string into hash?

I need to get all the words in a query (q=___) out of a (URL, I think) encoded string. Example line and my current plan: $queryString = 'pp=20&q=Finance/Banking/Insurance&qField=All&qMatch=any&qSort=smart&view=1' my %querys = $queryString =~ /(\S+)=(\S+)&?/g ; #Here I could use a tip on how to

Write hash of hashes to disk?

I've tried using DB_File open a hash and write a hash of hashes to disk, but this failed. I read in Perl Cookbook to "just use it as a regular hash" but from what I can tell this is not possible when speaking of complex structures like a hash of hashes. I'm currently dumping this structure to disk

proper way to start daemon

How to get single scalar to function cleanly

I have the following code to parse the line at the bottom of the email. Basically I want to take the date and convert it into something easy to say "is this within the last _ days" - the part of this that I think is particularly sloppy is the whole parsing below the split. Any tips (in particu
