Perl Beginner Question... 3

[SATech]

Having never used or even seen Perl, I just installed Active Perl 5.8 on my Win2K machine and have gotten as far as the PPM> prompt. How do I create a script in this environment?

Specifically, I want to create a script that simply returns the total # of entries and then averages the file size from a list of files contained in a file named 'files.txt'. This text file contains a hundred or so entries of files listed in the following format:

11/01/2003 04:42 PM 38124 c2ph.bat
06/03/2002 03:01 AM 5484 config.pl
11/07/2002 10:09 PM 1338 configPPM.pl
.
.
.

The third column is the file size that I need to average. How do I best approach this task???

Thanks in advance...sjv

PPM is used for configuring the perl environment, not running scripts in

create a script file, myscript.pl

#!c:/Perl/bin
print "hello world";

and run it from the command line, in the same directory as the file like the following

perl -c myscript.pl
perl myscript.pl

perl -c checks the syntax
and the second line runs it

You create scripts with an editor, e.g., Emacs, vi, Notepad.

What you want to do is trivial, but if you don't know the language at all, as you say, you should learn the language before you start programming in it. (To state the obvious.) Read a book or two. I suggest "Learning Perl" as a good one to start with. For more suggestions, try this:

Thanks for the replies...I have some programming experience but not with Perl. From what I gather it is very similar to C++. I am up against a timeline to get this done and was hoping I didn't have to re-invent the wheel. No time for reading books...thanks anyway!

Concerning editors, I like (and use) MED:

I'd start by taking a look at

http://docs.rinet.ru/P7/.

This is where I learnt perl from, although I did get to about day 13 before getting bored with the book but had learnt enough to be able to start writing fairly reasonable applications.

Thanks waiterm...this is exactly what I was looking for. Got most of it scripted but getting hung up on the 'split' command trying to read in the file size in the third column.

($date, $time, $ampm, $size, $filename) = split (/\s+/, $line);

\s+ = split on whitespace
