Can I set the password for a script??!!
 

Can I set the password for a script such that if I want to run that script I need to provide the correct password. Is it possible in bash scripting?

It's possible using the attribute available on the OS.
For example root script require you specify the password for have the privileges to run it.

ok. But how to do that?

Yes there are various ways both secure (encrypted) or easily discovered if not encrypted.
Here is a link that might help http://wiki.tcl.tk/3594
Try some google searches for more introductry information.

Simple way:

Create a user "runit"

The script you want to protect is /usr/bin/yourscript


Create the script "/usr/bin/doit" to contain

Make "doit" executable

When an ordinary user runs "doit", they'll be asked for "runit"'s password. If they enter it correctly. "yourscript" will run.

You could also look at sudo http://linux.die.net/man/8/sudo

pcunix,

Whatever you said I close to my requirement. But, I want to use a password for a specific script which means that I can run that script by providing that password rather than some other user's password.

So you create a "user" whose only purpose is to provide the context to run that script.

you can encrypt it using gpg -c <Script name>

But once it is decrypted, the user is free to examine it, copy it, etc.

Is it possible to use pam facilities? :twocents:
