Shell Programming and Scripting

Hello everybody!

This is my first time having to write a script so your help is most appreciated.Also i am a beginner when it comes to linux so please bare with me.Thanks in advance to all who will look into this for me.

I have to write a bash script that will show the free space on the hard disk and also to generate/propose a list of files to be deleted to free up space.
So far the part that shows the free space on the hard disk can be solved using the "df" command.As for the part with generating/proposing the list of files to be deleted i don't know how to proceed.

This is what I have so far:

#! /bin/bash
clear
df -h
exit

There are a lot of questions regarding how to find files here, search for find files with the search function as a start.

the thing is what are the search criterias for finding files and most important what files can be deleted in linux to free up space without killing the os?

Files that can be deleted to free up spaces are generaaly the log files specific to your application. Lets say, your application generates lots of log file on a certail directory and you know that those logs are not necessary if they are older than few days/weeks, then you can delete them or archive them, zip them...

use commands like, find, gzip, tar etc.

also, you should be able to archive old files from your application directory.

aren't there any other files,beside the log files, that can be deleted?i'm thinking that there must be some temp files like in windows that can be deleted.
