Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have written a script named scriptforhelp.sh where it has password added. Now I don't want any user to see the content.What tool/utility can I preferrably use?
For ssh access, use public keys instead of username/password. For mounting an smb share, use the "cred=" option in "sudo mount ..." commands where the file is only readable by effective user running mount.
If it is a password that the user of the script has access to, have the enter it in manually instead of putting it in a world readable script. E.G. don't use "mysql -u $USERNAME $DATABASE -p$PASSWORD" but instead use "mysql -u $USERNAME $DATABASE -p".
Or if you want to hide other users from seeing this users password, have the password read from the users HOME directory where other users can't read it.
Use polkit to allow a local session regular user to perform the action. (If there is a polkit authorization to do it)
Configure sudo to allow the user to perform that command, while requiring the users password, so the target password can remain a secret.
