Code:
#!/usr/bin/perl
use Config::Simple;
$cfg = new Config::Simple(syntax=>'ini');
$cfg->param('auth.user', 'sherzodR');
$cfg->param('auth.pass', 'mypass');
$cfg->write("new.cfg");
File structure:
#cat new.cfg ; Config::Simple 4.58 ; Tue Jul 7 11:20:58 2015 [auth] pass=mypass user=sherzodR
Reading the values:
#!/usr/bin/perl
use Config::Simple;
$cfg = new Config::Simple();
$cfg->read('new.cfg');
$user = $cfg->param("auth.user");
$pass=$cfg->param("auth.pass");
printf ("Username:%s Password:%s\n", $user,$pass);
On running:
#./testconfig.pl Username:sherzodR Password:mypass
Reading and then updating the values:
use Config::Simple;
$cfg = new Config::Simple();
$cfg->read('new.cfg');
$user = $cfg->param("auth.user");
$pass=$cfg->param("auth.pass");
printf ("Username:%s Password:%s\n", $user,$pass);
$cfg->param('auth.user', 'newuser');
$cfg->write("new.cfg");
On running:
#./testconfig.pl Username:sherzodR Password:mypass [[email protected]] ~/scripts #./testconfig.pl Username:newuser Password:mypass
