in reply to PIPE less


using system function we can achieve this.
See the following example code.
use strict; use warnings; use Getopt::Std; . . . my %option=(); getopts("hwmyc:",\%option); . . . if(defined $option{h}) { system("less help_file"); #system("cat help_file | less"); #system("echo "this is help file"|less"); } . . .
--$ugum@r--
