Hello.
I'm new to Perl and I am not sure how to interpret command line arguments in the program. I am writing a program similar to the Unix utility 'tail' and need to check if first argument is '-1' ([dash]1) or any arbitrary number of lines to output. How would I write an 'if' statement to check for the dash (-) and a number? Checking for the dash is trivial below.
How can I parse the dash with a number attached? Any numerical value?
Sample program run below:
File 'samp.txt' contains:
Hello World
This
Is
A
Test

asp-perl
ASP-PERL(1p) User Contributed Perl Documentation ASP-PERL(1p)NAME
asp-perl - Apache::ASP CGI and command line script processor
SYNOPSIS
asp-perl [-hsdb] [-f asp.conf] [-o directory] file1 @arguments file2 @arguments ...
-h Help you are getting now!
-f Specify an alternate configuration file other than ./asp.conf
-s Setup $Session and $Application state for script.
-d Set to debug code upon errors.
-b Only return body of document, no headers.
-o Output directory, writes to files there instead of STDOUT
-p GlobalPackage config, what perl package are the scripts compiled in.
DESCRIPTION
This program will run Apache::ASP scripts from the command line. Each file that is specified will be run, and the $Request->QueryString()
and $Request->Form() data will be initialized by the @arguments following the script file name.
The @arguments will be written as space separated words, and will be initialized as an associate array where %arguments = @arguments. As
an example:
asp-perl file.asp key1 value1 key2 value2
would be similar to calling the file.asp in a web environment like
/file.asp?key1=value1&key2=value2
The asp.conf script will be read from the current directory for parameters that would be set with PerlSetVar normally under mod_perl. For
more information on how to configure the asp.conf file, please see < http://www.apache-asp.org/cgi.html >
