This Curl cheat sheet contains commands and examples of some common Curl tricks.
Curl is a tool for transferring data between servers, supporting protocols, including:
-o <file> # --output: write to file
-u user:pass # --user: authentication
-v # --verbose: Make curl verbose during operation
-vv # more verbose
-s # --silent: don't show progress meter or errors
-S # --show-error: When used with --silent (-sS), show errors but no progress meter
-i # --include: include HTTP headers in the output
-I # --head: header only
-X POST # --request
-L # If the page redirects, follow the link
-F # --form: HTTP POST data for multipart/form-data
# --data: HTTP post data
# URL encoding (eg, status="Hello")
-d 'data'
# --data pass file
-d @file
# --get: send -d data via get
-G
-A <str> # --user-agent
-b name=val # --cookie
-b FILE # --cookie
-H "X-Foo: y" # --header
--compressed # use deflate/gzip
