You can create function something like this and call

Code:
#!/bin/bash



url(){
    if [ ! -z "$1" ]; then
        wget "$1" >/dev/null 2>&1 
        [ "$?" -eq 0 ] && echo "Url : $1 exists..." || echo "Url : $1 doesn't exists.."
    else
        echo "No Arguments..exiting" & exit
    fi
}


url "https://www.unix.com"
url "http://www.unixaaaa.com"

URL=https://mybank.net:8443/Services/com/Notification.jws

This only checks for the hostname / port number [https://mybank.net:8443]. What about the rest of the URL / page [/Services/com/Notification.jws] if it exists or not?

How can we check that?
