I had need to ensure a Url was valid.. So i decided to write a function that I could use in my bash session for just that type of thing:
followedUrlValid()
usage()
{
echo " -- Usage for followedUrlValid ---
\$1 = the account you wish to login to
looks for the http_code from getting the url if valid returns true if not returns false
if the url has redirects it'll follow the redirects
"
}
if [ -z "$1" ]; then
echo >&2 'Need 1 parameters which are not empty'
usage
return 1
fi
returnval='false'
value=$(curl -o /dev/null -LIsw '%{http_code}\n' $1)
if [ "$value" = 200 ]; then
returnval='true'
fi
echo "$returnval"
Below you can see two uses of this function in your bash/zsh prompt
followedUrlValid https://google.com
true
followedUrlValid https://invalidurl.okiedokie
false
