REST service to execute series of command lines at specific moments of time

Usage: 

Arguments:
  <LISTEN_ADDRESS>
          Socket address to listen for incoming connections.
          
          Various types of addresses are supported:
          
          * TCP socket address and port, like 127.0.0.1:8080 or [::]:80
          
          * UNIX socket path like /tmp/mysock or Linux abstract address like @abstract
          
          * Special keyword "inetd" for serving one connection from stdin/stdout
          
          * Special keyword "sd-listen" or "sd-listen-unix" to accept connections from file descriptor 3 (e.g. systemd socket activation)

  [PREFIX]
          Prepend this command to all executed chunks

Options:
      --unix-listen-unlink
          remove UNIX socket prior to binding to it

      --unix-listen-chmod <UNIX_LISTEN_CHMOD>
          change filesystem mode of the newly bound UNIX socket to `owner`, `group` or `everybody`

      --unix-listen-uid <UNIX_LISTEN_UID>
          change owner user of the newly bound UNIX socket to this numeric uid

      --unix-listen-gid <UNIX_LISTEN_GID>
          change owner group of the newly bound UNIX socket to this numeric uid

      --sd-accept-ignore-environment
          ignore environment variables like LISTEN_PID or LISTEN_FDS and unconditionally use file descritor `3` as a socket in sd-listen or sd-listen-unix modes

      --tcp-keepalive <TCP_KEEPALIVE>
          set SO_KEEPALIVE settings for each accepted TCP connection.
          
          Value is a colon-separated triplet of time_ms:count:interval_ms, each of which is optional.

      --tcp-reuse-port
          Try to set SO_REUSEPORT, so that multiple processes can accept connections from the same port in a round-robin fashion

      --recv-buffer-size <RECV_BUFFER_SIZE>
          Set socket's SO_RCVBUF value

      --send-buffer-size <SEND_BUFFER_SIZE>
          Set socket's SO_SNDBUF value

      --tcp-only-v6
          Set socket's IPV6_V6ONLY to true, to avoid receiving IPv4 connections on IPv6 socket

      --tcp-listen-backlog <TCP_LISTEN_BACKLOG>
          Maximum number of pending unaccepted connections

  -h, --help
          Print help (see a summary with '-h')
