Hi all,

If you look at wat i wan is basically, having a statement being wrtting something like :

Daemon Started     [ Done ]
Daemon Listening   [ Fault ]

all in the same vertical line and horizontal line of that statement.

today i could only do something like :

Daemon Started
                                     [Done]
Daemon Listening
                                     [Fault]

it basically in same vertical line but not in same horizontal line.
it has to skip 1 line.
i do it by adjusting "echo -e" & "echo -en"

can someone explain how can i achieve something like picture above.

Hi, the mechanism for how the init.d scripts works changes on your distribution. In Redhat and Fedora, its done with a script in /etc/init.d calling /etc/rc.d/init.d/functions which has a bash function in it called deamon I think.

Anyway, to achieve what you want, the left hand side could be done with something like:

echo -n Deamon

then the right hand side could be done with something like:

echo Success

If you want to color code it, you can follow this web page for examples:

Thanks for replying,

I have actually tried that but it doesnt really get a proper vertical line, example all i get is :

Starting Deamon      [Done]
starting Listining to Deamon      [Fault]

It is based on the length of characters on the left then only on the right prints out based on the tabs or spaces.
but thats not what or how i would like to have it.
i practically am trying to hv it in sync in 1 line

check printf manual page instead of using echo

If you want to replicate the OK/FAILED messages at init (like in your posted pic), you could do something like:

#!/bin/bash

# source function library
. /etc/init.d/functions

# run your prog/script/command
action $"Running my prog: " /path/to/prog

It will evaluate the exit code from your prog and show either OK or FAILED.

If you want to do your own message, then just look at the /etc/init.d/functions and see what they do with RES_COL, MOVE_TO_COL and SETCOLOR_*
