bash: echo something to right end of window (right aligned)

Question

I am looking for producing success/fail messages which are right aligned in bash. An example would be what apache2 produces on executing: sudo /etc/init.d/apache2 relo

Have a look at this thread, might be interesting : how to write a bash script like the ones used in init.d?

On Linux CentOS 6.5, i'm using the /etc/init.d/functions file:

#!/bin/bash
. /etc/init.d/functions # include the said file

action "Description of the action" command

exit 0

assuming command returns 0 on success, positive value if an error occurs. To let the script be easy to read, i use a function call instead of the whole command.

Here is an example:

#!/bin/bash

. /etc/init.d/functions

this_will_fail()
{
    # Do some operations...
    return 1
}

this_will_succeed()
{
    # Do other operations...
    return 0
}


action "This will fail"     this_will_fail
action "This will succeed"  this_will_succeed

exit 0

resulting in: (note : french locale ;-) )

Hope it'll help !
