# This is a very simple script, which demonstrates how ‹curl› can be
# used to send data to a remote server, using so-called ‹POST›
# requests. This script can be really useful in case you want to
# send the output of a command or the content of a plain text file
# to someone across the internet.

# We use a web service called ‹ix.io› which will hold text for us,
# and lets us send it using a simple POST request. Basically a
# no-frills pastebin.

echo hello world | curl -F 'f:1=<-' http://ix.io

# The ‹-F› argument to ‹curl› is short for ‘form’, and uses the
# ‹POST› protocol in a manner similar to how a web browser would use
# it to send data you filled in an HTML form. ‹f:1› is the name of
# the key and the ‹<-› is an instruction to read the value for that
# key from ‹stdin›.

# After the script runs, you can try fetching (with just ‹curl›) the
# resulting URL. You should get back ‹hello world›.

# That's all for the user-level part, let's do some C:
#
#     $ micro ghbn.c
