I, multiple times per day, find myself wanting to find out what headers I get back on a URL but I don't care about the response payload. The command to use then is:
curl -v https://www.peterbe.com/ > /dev/null
That'll print out all the headers sent and received. Nice and crips.
So because I type this every day I made it into a shortcut script
cd ~/bin echo '#!/bin/bash > set -x > curl -v "$@" > /dev/null > ' > c chmod +x c
If it's not clear what the code looks like, it's this:
#!/bin/bash
set -x
curl -v "$@" > /dev/null
Now I can just type:
c https://www.peterbe.com
Or if I want to add some extra request headers for example:
c -H 'User-Agent: foobar' https://www.peterbe.com
This matters if you type it a lot.
Also, the -I means it does a HEAD request and the server might respond differently. For example the Content-Length header might be wrong/different.
