Code:
#!/bin/bash

if [curl http://www.appleturns.com/ > grep -q "mass backsies"]
then
      echo "Jack is still away"
else
      echo "He's back!"
fi

I'm close I think. How do I search this page for the specified text, then do something if it's there?

Thanks,

I'd dump it to file, grep the file, then remove the file.
This uses grep to count the matches found and drops that number into a var as an int.
then just test the int.

Code:
#!/bin/bash

curl http://www.appleturns.com/ > temp.html
c=`grep -c "mass backsies" temp.html`


if [ "$c" -ge "1" ] 
then
echo "He's back!"
else
echo "Jack is still away"
fi

rm temp.html

I think you want a pipe there , not a redirect. That will send the output of the "curl" command directly to "grep" via STDIO without creating an intermediate file. Or something like that.

Try

Code:
if [curl http://www.appleturns.com/ | grep -q "mass backsies"]

OK, here's my final solution. I installed the command line tool growlnotify that can pass a message to Growl. This script runs every hour:

Code:
#!/bin/bash

curl -s http://www.appleturns.com/ > temp.html
c=`grep -c "mass backsies" temp.html`

if [ $c == 0 ]
then
        /usr/local/bin/growlnotify -s "Jack Alert" -m 'Jack is Back!'
fi

rm temp.html

Thanks for the help!

OK, I was so pleased with how this worked, I'd like to modify it to detect whenever this website is updated. I see the pseudo-code as follows:

1. Check if website has changed using Grep
2. If changed, display alert and then re-write the text searched for in Grep.

I think I can muddle through re-writing the Grep expression, but I'm not sure how to dynamicaly re-write the script to display the new search string. Should I use something like cat $theScript > file.sh? Is there a better way?

Thanks,
