Feed username/password to curl without temporary files and without showing in process list

curlum.sh

# usage: curlum <username> <password> <curl args...>
curlum () {
  user="$1"
  pass="$2"
  shift 2
  curl --config /dev/fd/3 "$@" 3<<EOF
--user $user:$pass
EOF
}

# example
USER=foo
PASS=bar
curlum $USER $PASS http://localhost:1234/index.html

Works also together with --data @- like this:

SECRET="1v4yu991h4c"
curlum $USER $PASS --data @- http://localhost:1234/index.html <<EOF
foo=bar&super=$SECRET
EOF

Apparently the --netrc-file option was added in curl 7.21.5. Script updated to use --config instead.
