shell script with dialog

sqn · 04-06-2004, 01:19 PM

I have this folowwing code:

Code:

#!/bin/bash
dialog --title "Tunnel name" --backtitle "mod_gre tunneling script created by silviu -silviu@umbra.ro" \
       --inputbox "Enter the name of the tunnel \nplease use whole words, no spaces alowed\nand try to keep at most 8\
                characters" 8 60  > /tmp/input.$$

sel=$?

na=`cat /tmp/input.$$`
case $sel in
  0) ifconfig > /root/grepin |grep -n $na /root/grepin > /root/grepout |cat /root/grepout ;;
  1) echo "Cancel is Press" ;;
  255) echo "[ESCAPE] key pressed" ;;
esac

rm -f /tmp/input.$$

i need to know where i do wrong, because the script is not giveing me anythig.

Code:

ifconfig > /root/grepin |grep -n $na /root/grepin > /root/grepout |cat /root/grepout

this command is working perfectly but putit in this script doesn't work

thx in advance

In what way 'isn't giving me anything'? Not displaying the box, or not behaving as expected?

it's not behaving as aspected
it does not run this command:

Code:

ifconfig > /root/grepin |grep -n $na /root/grepin > /root/grepout |cat /root/grepout

Try this:

Code:

ifconfig | grep -n $na

Simpler. Let us know whether it works or not.

In your example you are redirecting stdout twice on two commands with the ">" and "|". I would expect your results to be undefined. (Anything could happen!)
