Top Forums Shell Programming and Scripting A twisted feature of sort when called in awk Post 302377494 by nrgbooster on Friday 4th of December 2009 07:47:36 AM

Sorry, I'm lost here...

Quote:
The command begins executing when the pipe opens.
If this is the case how "sort" can know the end of data it is to process? For example, if we run "cat file | sort" in shell the second command sort will get the entire input (at least I felt so) from cat before it kicks off.

By the way, I was not meant to see
Code:
hello world!
hello world!
hello world!
a
b
c

I was just going to confirm which will be displayed first, "hello world"(just one line) or a sorted "a b c".

NAME
CPANPLUS::Shell - base class for CPANPLUS shells SYNOPSIS
use CPANPLUS::Shell; # load the shell indicated by your # config -- defaults to # CPANPLUS::Shell::Default use CPANPLUS::Shell qw[Classic] # load CPANPLUS::Shell::Classic; my $ui = CPANPLUS::Shell->new(); my $name = $ui->which; # Find out what shell you loaded $ui->shell; # run the ui shell DESCRIPTION
This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS" shell. Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic loading class), so please consult the documentation of your shell of choice.
