Enable Tab to pre-populate file name in vim

If you create a new user account in linux, then pressing Tab won't bring a filename with it's initials. To enable Tab you need to edit the passed file. Let's see how we can do it. 1. Create a user with:

useradd -d /home/testuser -m testuser

Here -d takes the user directory path and -m creates the user directory. you can use -p to set a password in the command. 2. To set a password use:

passed testuser

Then enter your password and retype it. 3. Now if you go to /home/testuser directory you will see .bashrc and .profile files. .bashrc file is used whenever a new tab opened in the console and .profile is used only for the first time while an authentication is done. Now we will change the /etc/passwd file. open the file and you will see your newly created user is listed there. There is sh beside his name. Change it to bash, like the following:

testuser:x:1003:1004::/home/testuser:/bin/bash

Now you will see that Tab is working in your console under your new user.
