Linux script with curl to check webservice is up

I have a webservice provided at

http://localhost/test/testweb


I want to write a script to check if webservice is up with curl

If there a curl parameter given, returns
200 OK
ok true false so that I can use it is if-else block in linux script

Answer
curl -sL -w "%{http_code}\\n" "http://www.google.com/" -o /dev/null
  • -s = Silent cURL's output
  • -L = Follow redirects
  • -w = Custom output format
  • -o = Redirects the HTML output to /dev/null

Example:

[~]$ curl -sL -w "%{http_code}\\n" "http://www.google.com/" -o /dev/null
200

I would probably remove the \\n if I were to capture the output.
