Check if url returns 200 using bash

I need to check if the remote file exists based on the url response by doing:

curl -u myself:XXXXXX -Is https://mylink/path/to/file | head -1

What can give something like these:

'HTTP/1.1 200 OK
'

or

'HTTP/1.1 404 Not Found
'

Now, I want to extract the http status code like 200 from the resulting string above and assign the number to a variable. How can I do that?

Nice and simple:

curl --output /dev/null --silent --head --fail http://google.com

Use the -o option to send the headers to /dev/null, and use the -w option to output only the status.

$ curl -o /dev/null -u myself:XXXXXX -Isw '%{http_code}\n' https://mylink/path/to/file
200
$

If you intended to capture the status to a variable, you can omit the newline from the format.

$ status=$(curl ... -o /dev/null -Isw '%{http_code}' ...)

Use grep:

curl -u myself:XXXXXX -Is https://mylink/path/to/file | head -1 | grep -o '[0-9][0-9][0-9]'
