Curl Usage

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar File to save response cookies to.

-d, --data Send specified data in POST request. Details provided below.

-f, --fail Fail silently (don't output HTML error form if returned).

-F, --form <name=content> Submit form data.

-H, --header

Headers to supply with request.

-i, --include Include HTTP headers in the output.

-I, --head Fetch headers only.

-k, --insecure Allow insecure connections to succeed.

-L, --location Follow redirects.

-o, --output Write output to . Can use --create-dirs in conjunction with this to create any directories specified in the -o path.

-O, --remote-name Write output to file named like the remote file (only writes to current directory).

-s, --silent Silent (quiet) mode. Use with -S to force it to show errors.

-v, --verbose Provide more information (useful for debugging).

-w, --write-out Make curl display information on stdout after a completed transfer. See man page for more details on available variables. Convenient way to force curl to append a newline to output: -w "\n" (can add to ~/.curlrc).
