Why do you need a script? Did you consult the man pages.
Code:
yum remove package
yum erase package
yum downgrade package

Actually I want to uninstall/install a package using yum through shell scripting.
I tried using the above mentioned command but didn't work for me.
can you please send a proper code written in shell scripting?
I'll be highly thankful for your cooperation.

If the command doesn't work from the command line, it's not likely to work from a script. Post the error you got.

It is working fine from command line
but not from script.

That tells us nothing useful. We could guess all day at millions of things that might keep a script from working, but the chances that any of them would solve your problem are probably less than 1 in a billion.
  1. Show us the exact commands you are using on the command line that work (in CODE tags).
  2. Show us the exact contents of your shell script (in CODE tags).
  3. Show us exactly how you invoke your shell script (in CODE tags).
  4. Show us the exact output (including any diagnostic messages) produced by your shell script (in CODE tags).
With that information, we stand a MUCH better chance of being able to make suggestions that might help you resolve your problem.

The error I'm facing is:

Code:
[root localhost Desktop]# ./remov.sh
bash: ./remov.sh: /bin/sh^M: bad interpreter: No such file or directory
[root localhost Desktop]# ]

I'm trying to run :
Code:
[root localhost Desktop]# yum remove -y samba

The content of my .sh file :
Code:
#!/bin/sh
#yum remove -y samba
