Bash script output to console without login

m.dam · 12-30-2010, 12:18 PM

Hi all,

i'm looking for a way to output a bash script to the console before login.
It should be executed after boot in rc.d scripts with the output on the console0. It is for a asterisk box.

This is the script. It use the watch command to output the active calls on the box in realtime.

Code:

watch "asterisk -vvvvvrx 'show channels verbose'"

Btw, happy new year!

So what's the question?

Scripts run from boot scripts have stdout and stderr connected to the console. IDK asterisk and whether it has virtual terminals but I find it useful not to start a virtual terminal on the /dev/console device (tty1) so the boot script messages continue being displayed.

dmesg will show the boot up messages
or you can look in /var/log/* for what happened during boot up

Maybe i wasn't so clear.

I need a way to execute the script on system boot and show the output of the script in console without login.

Thanks!

Any reason not to create a rc.d script to do it?

Yes, this is the way, but how can i show the output in the console ?
How can i redirect the output of the script to tty1 or tty2 ?

How about just putting a "> /dev/tty1" when you do your variable output in the script? Or (better) put it through "tee", so it goes to both the log files and the console/terminal/whatever
