Just to add a reference to the relevant part of the manual:

Quote:

print items | command

It is possible to send output to another program through a pipe instead of into a file.
This redirection opens a pipe to command, and writes the values of items through this pipe to another process created to execute command.
The redirection argument command is actually an awk expression. Its value is converted to a string whose contents give the shell command
to be run.

For example, the following produces two files, one unsorted list of BBS names,
and one list sorted in reverse alphabetical order:

Code:

awk '{ 
    print $1 > "names.unsorted" 
    command = "sort -r > names.sorted" 
    print $1 | command 
    }' BBS-list

So, as already stated, it's like:

Code:

zsh-4.3.12[sysadmin]% print -l 3 1 2 | sort
1
2
3

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
