Scripting makes your life easier !

Thought of the day was make your life easier... Learn and Develop

Why ??


A day before yesterday i ran into situation where i thought how can I've a check in place which can -

• Check the status of service running on the server 
• And the utilization level of a particular file system.

Though i'm a newbie in scripting and still exploring the world of automation but i was able to write a small code which does the required work.

What it does:

It checks the service status of a particular Linux OS service & the utilization level of the specified file system and send the output at the specified mail id.

How you can use it:

1) Copy it and save it in a .sh or .py format
2) Change the file permission to executable. You can do it by using the command

# chmod 700 <file_name>

3) You can either execute it manually or schedule it via cron / autosys jobs.

Happy Learning!
