A Simple Bash Script To Manage Linux Services ~ ServerComputing

This is a simple script to manage all the system services in your Linux operating system. The script can interact with the user and manage the services in the linux OS. With the help of this simple bash script you can start, stop, reload, and know the current status of all the services in your server like Squid, Samba, postfix, dovecot, apache, FTP, VNC, DHCP, NFS, iptables, etc. All you need to select the task and input the exact service name(daemon name). And the script will do the task.

For example if you need to reload the squid service, first run the script and select "4" (for reloading a service), and type the service name "squid". Now the script will reload the squid service for you. You can edit the script and add more options as your needs.

This script is tested in CentOS and should work on RPM based distributions like Fedora and Redhat Linux, etc.
