[SOLVED] BASH script issue w/ popout terminal...

vankirk88 · 10-22-2011, 11:13 AM

Hiya all, first post here so be gentle :P

I've been taking time to learn bash scripting and enjoying messing with my network so I figured I'd take the commands I use the most often and write up a bash script with them (airodump, aircrack, aireplay, dsniff, nmap, arpspoof, etc.)

Long story short i'm having a major issue with this arpspoof script that i'm trying to write and after tirelessly trying to find a answer, just can't seem to get it to work.

Code:

#!/bin/bash
clear
read -p "Run route -n? (y/n) " dgateway
    if [ dgateway = y ]; then
        sudo xterm -e "route -n" &
        echo "Moving along..."
    fi
....more code from here....

I've been trying to learn how to do this via several older books and just picking apart other peoples scripts. So most of the time i'm not even sure if the information still applies.

What happens for me is it briefly opens a window (can just see it flash) and moves along with the rest of the script. What I want to happen is it pop up a window and leave it be while the script moves along. Really got me annoyed, hehe.
Any help here would be greatly appreciated.

One solution (not tested) is to start xterm with -e 'bash --rcfile <path/to/your/custom script>' with your custom script written to run the route -n command. This works because bash, unlike route -n, does not exit until the interactive user makes it.

How about using the -hold option:

Quote:

-hold Turn on the hold resource, i.e., xterm will not immediately destroy its window when the shell command completes. It will wait until you use the window manager to destroy/kill the window, or if you use the menu entries that send a signal, e.g., HUP or KILL.

Thanks to both of you for your answers...Finally got it working the way I wanted with the -hold command, tried using it before but I think I had the syntax wrong.

Also, thats interesting catkin, gave me something to play around with...didn't quite follow, but I got the basic concept of what you were saying, should come in handy later.
