Top Forums Shell Programming and Scripting Perl : Perl equivalent to the ksh | and ; Post 302874983 by popeye on Monday 18th of November 2013 08:09:22 AM

To change
primary
Factory CTS 1.9.0(46) P1
*Slot 1 CTS 1.10.2(42) P1

To
primary *Slot 1 CTS 1.10.2(42) P1

Simplified, to do this in shell
Code:
z=`sed '/Factory/d' xyz |  tr '\012' ' '

Notice how piping the commands together I easily applied the desired result to "z".

Lets go one step further, if I wanted a specific field, again simplified
Code:
z=`sed '/Factory/d' xyz |  tr '\012' ' ' | awk  '{print $5}'

Here Id isolate the version and put in in "z"

Im sure a perl wizard would be able to do this in about as many characters as I used in shell. This is what Im after. My question is not so much related to how to execute this particular function, but how to learn how to nest/pipe commands together.

NAME
Class::Factory::Util - Provide utility methods for factory classes SYNOPSIS
package My::Class; use Class::Factory::Util; My::Class->subclasses; DESCRIPTION
This module exports a method that is useful for factory classes. USAGE
When this module is loaded, it creates a method in its caller named "subclasses()". This method returns a list of the available subclasses for the package. It does this by looking in @INC as well as the directory containing the caller, and finding any modules in the immediate subdirectories of the calling module. So if you have the modules "Foo::Base", "Foo::Base::Bar", and "Foo::Base::Baz", then the return value of "Foo::Base->subclasses()" would be "Bar" and "Baz". SUPPORT
