Tab filename completion

When you use the bash shell on Linux it will complete commands and file names for you if you type the 'TAB' key. The default behaviour is:

Example:
 * 1) You type in the start of the command or filename.
 * 2) You hit TAB.
 * 3) The shell will fill in as much as it can and beep.
 * 4) Hit TAB again and it shows you all possible matches.
 * You want to start firefox and type only firef and then the 'TAB' key.
 * You want to know which commands starting with 'f' exist, so you type 'f' and then the 'TAB' key twice.

 * 1) You type in the start of the command or filename.

All that needs to be done is:

set show-all-if-ambiguous on
 * 1) Edit /etc/inputrc
 * 2) Add the line:

= Problems = Tab filename completion does not work in some scenarios. sudo cp /root/ and then the 'TAB' key. bash will try to complete the filename, but you as a user are not allowed to see the files in the /root folder. Bash filename completion will not work for this reason.
 * Example: You are an ordinary user. You oPen a console and type

scp root@192.168.0.1:/tmp/ then the 'TAB' key does not work.
 * Example: You want to copy from the network
