yes. your code is working perfectly. I am using this sample peice for puppet automation. so for awk part I don't hard code anything. I will write all vlaues to some other yaml file and will ivoke that value variable into puppet awk function.

so my code would be

Code:
awk '/kernel.sem/ { if(($3 + 0) < $value) sub($3, "$value") } 1' /etc/sysctl.conf >> /etc/sysctl.conf.bkp

so what my doubt is, when I use $value parameter should I still use +0 on this

NAME
puppet-master - The puppet master daemon SYNOPSIS
The central puppet server. Functions as a certificate authority by default. USAGE
puppet master [-D|--daemonize|--no-daemonize] [-d|--debug] [-h|--help] [-l|--logdest file|console|syslog] [-v|--verbose] [-V|--version] [--compile node-name] DESCRIPTION
This command starts an instance of puppet master, running as a daemon and using Ruby's built-in Webrick webserver. Puppet master can also be managed by other application servers; when this is the case, this executable is not used. OPTIONS
Note that any configuration parameter that's valid in the configuration file is also a valid long argument. For example, 'ssldir' is a valid configuration parameter, so you can specify '--ssldir directory' as an argument. See the configuration file documentation at http://docs.puppetlabs.com/references/stable/configuration.html for the full list of acceptable parameters. A commented list of all configuration options can also be generated by running puppet master with '--genconfig'. --daemonize Send the process into the background. This is the default. --no-daemonize Do not send the process into the background. --debug Enable full debugging. --help Print this help message. --logdest Where to send messages. Choose between syslog, the console, and a log file. Defaults to sending messages to syslog, or the console if debugging or verbosity is enabled. --verbose Enable verbosity. --version Print the puppet version number and exit. --compile Compile a catalogue and output it in JSON from the puppet master. Uses facts contained in the $vardir/yaml/ directory to compile the catalog. EXAMPLE
puppet master DIAGNOSTICS
When running as a standalone daemon, puppet master accepts the following signals: SIGHUP Restart the puppet master server. SIGINT and SIGTERM Shut down the puppet master server. SIGUSR2 Close file descriptors for log files and reopen them. Used with logrotate. AUTHOR
