[Bash] Ending Script

[daryll1]

Hi, as a bit of background, My Uni have lately implemented a CGI script so you have to log in to be able to use the wireless. This would be OK but they are terrible programmers and instead of timing out after a period of inactivity it will time out after 570 seconds. Again I wouldn't mind this but to re-connect I have to completely disconnect from the wireless, this is just a pain.

This problem can be overcome by signing out after a period of time and re-signing in. I have written a basic script so far which uses Lynx to open the CGI and sign you in, but, I am having a problem ending the script once run.

I am thinking about calling the script from a second script, passing the process id back and killing it from the first script.

You will find my code below, if anyone knows a better way of doing this or thinks it isn't worth bothering with then please let me know.

Cheers,
Daryll

if [ ! -e input ]; then
echo "Enter username:"
read USERNAME
s=$USERNAME

echo "# Command logfile created by Lynx 2.8.7pre.6 (23 Jun 2009)

for i in $(seq 0 $((${#s} - 1))); do
	echo "key ${s:$i:1}" >> "input"
done

printf "key <tab>\n" >> input

echo "Enter password:"
read PASSWORD
s=$PASSWORD

for i in $(seq 0 $((${#s} - 1))); do
	echo "key ${s:$i:1}" >> "input"
done

printf "key ^J
key ^J
key y" >> input
fi

lynx -cmd_script=input -exec 'http://172.21.254.254/modules/auth/cgi-bin/ssllogin/login.cgi'
exit

How I am trying to do it at the moment.

test1.sh

lynx 'http://localhost'

test2.sh

source test1.sh &
DAR=$!
echo 'Running in background...'
sleep 5
echo 'Quitting...'
kill $DAR
return
