The `apaste` program

apaste is a program that reads one or more files, or its standard input, and sends the data to an apasted server.

Interface

     apaste [ -S | -s ] [ -C cadir ] [ -d server[:port] ] [ -r rtimeout ] [ -w wtimeout ] file...

apaste connects to a remote server via a plaintext or TLS-secured connection, expecting to find an apasted server at the other end.
For every file given as argument, it sends the contents of file over the network. If file is - (dash), then apaste's stdin is transmitted until EOF.
The server answers with a blob of six printable characters, named a slug. Depending on the server configuration, it may embed the slug in a complete URL, for easy copy-paste into a browser; or it may embed it in another way.
apaste prints the slug to its stdout, then exits 0.

0: Success. The data has been recorded by the server and available in some way as indicated by the slug.
100: Bad usage. apaste was run in an incorrect way.
111: System call failed. This usually signals an issue with the underlying operating system, or with the network in some way.

-S: Normal, plain text connection to the server, even if the built-in default is TLS. The built-in default can be changed via the --with-default-tls or --without-default-tls options to configure.
-s: TLS connection to the server, even if the built-in default is plain text. The built-in default can be changed via the --with-default-tls or --without-default-tls options to configure.
-C cadir: When using a TLS connection, use cadir as the directory containing the hashed names of the trust anchor certificates (used for verifying the server's certificate chain). The built-in default can be changed via the --with-default-cadir option to configure.
-d server[:port]: Connect to server server, port port. The built-in defaults can be changed via the --with-default-server, --with-default-port, and --with-default-tlsport options to configure.
-r rtimeout: If the server isn't answering with a slug within rtimeout milliseconds, give up. The default is 0, meaning infinite: apaste will wait forever for a server reply if necessary.
-w wtimeout: If the server hasn't accepted all the data within wtimeout milliseconds, give up. The default is 0, meaning infinite: apaste will take as much time as it needs to send its data.

apaste is only a wrapper around s6-tcpclient (for plain connections) or s6-tlsclient (for TLS-tunneled connections), and apastec that is the real client. The point of apaste is to provide a short command line with good compiled-in defaults; make sure your defaults are correct at configure time when building the apaste package.
-, i.e. stdin, cannot be mentioned several times as an argument. It can be transmitted with other files, but cannot be duplicated.
