Bash Script- command on exit

PDock · 12-22-2005, 05:48 AM

Is there a way to 'pre-fill' the command line when your bash script exits?

If your scripts contains a test like:

Code:

if [ ! -f /etc/HOSTNAME ]; then
clear
echo "You do not have a /etc/HOSTNAME file. You need to setup your network first!"
echo "Come back after setting up your network."
NEED COMMAND HERE=/sbin/netconfig
exit
fi

Such that after the script exits the command line would be prefilled with the 'variable' set by the script. ie

Code:

yourprompt# /sbin/netconfig

Note: I don't want the script to chain another script; just exit and prefill if possible.

thanks in advance

sorry i am at work now so i am not infront of linux ;(

you could try something like this

Code:

if [ ! -f /etc/HOSTNAME ]; then
clear
echo "You do not have a /etc/HOSTNAME file. You need to setup your network first!"
echo "Come back after setting up your network."
xterm -e 'echo /sbin/netconfig' &
exit
fi

--edit--

sorry read it poorly, mine was not the answer to the question

The above answer suggested by heema will of course not do the trick either. It will simply echo /sbin/netconfig on xterm and exit. As far as I know, there is no way. Why don't you just suggest running /sbin/netconfig from inside the script?

Thanks for the replies, if no one comes up with and answer; quess telling what to execute is only answer.
Hate to admit my age, and at my age can only half remember a DOS keypad keystroke key??? command that achieved what I am looking for in bash.

Again thanks

Of course you could offer to run the command for the user:

Code:

if [ ! -f /etc/HOSTNAME ]; then
clear
echo "You do not have a /etc/HOSTNAME file. You need to setup your network first!"
echo "Come back after setting up your network."
echo -en "\n Do you want to run /sbin/netconfig now (y/n) ?"
read ANSWER
[ "x$ANSWER" = "xy" ] && /sbin/netconfig
exit
fi

Worth the trip here, thanks alienDog had never seen y/n tested as "x$ANSWER" = "xy" , pretty slick.
