meow v$VERSION
An easy tool for making requests using cURL and following redirects

Usage:
  $0 [options...] <method> <URL>
  $0 [options...] <URI>

When the request can have a body (methods POST, PUT, DELETE, PATCH), then it is read from stdin.
When a successful response has a body, then it is written to stdout.
If the response cannot has a body (methods HEAD, PUT, TRACE), then its headers is written to stdout.
If cURL returns a non-zero exit code, its output is written to stderr without changes.
Methods can be specified in any case (post, POST, POsT, etc).

Allowed methods:
  get (defalut)
  head
  post
  put
  delete
  connect
  options
  trace
  patch

Options:
  -a, --useragent   "<useragent>"    - set a user-agent for the request
  -c, --cookie      "<cookie>"       - set a cookie for the request
  -C, --save-cookie <filename>       - save a cookie from the response to the file
  -h, --header      "<key>: <value>" - set a optional header for the request
  -H, --head                         - get response head instead of body
  -p, --proxy       <proxy>          - use the proxy
  -r, --referrer    <referrer>       - set an address making the request
  -t, --type        <type>           - set a type of the sending content
  -v, --version                      - show a version of the tool
