    Yes. If you run this script and checksitestatus.sh and use http://google.com it'll say site is up. If you type http://googlex.com it'll say site is down.

    You would have to install lynx to from the repository with:

    $ sudo apt-get install lynx

    The script (checksitestatus.sh):

    #!/bin/bash

if [[ $# -eq 0 ]] ; then
    echo 'Missing parameter - site to check... exiting.'
    exit 0
fi

site=$1    
siteisdown=$(lynx -dump $site 2>&1 | egrep 'Alert!: Unable to connect to remote host.')

if [[ "$siteisdown" ]]
then
    echo "Site is down"
    # any other code here
else
    echo "Site is up"
    # any other code here
fi
