Pass a string as stdin.
Pipe from the right command to the left command. Returns the left command modified.

captureFd for stdout.

Capture the output of the fd of the command strictly, err if the command exits with a non-zero exit code.
Capture the output of the fd of the command strictly. Ignores process exit code.
Capture the output of the fd of the command lazily. If the process exits with a non-zero exit code, reading from the bytestring will throw CmdException. Garbage collection will close the pipe.
Capture the output of the fd of the command lazily. Ignores process exit code. Garbage collection will close the pipe.
Pass an argument of the form /proc/self/fd/<n> to the process,
where n is the reader end of a pipe which the passed string is written to.
value
mq :: (QuickCmd a, ToByteString b)=> bThe path to the executable, uses PATH
-> aEither a Cmd, an
IO (), or a function that takesCmd -> Cmd, String or ByteString
mq "cat" "/dev/null" (pipeArgIn 1 $ mq "cat" "/dev/null") <<< "somestr"The first argument is the path, and the subsequent arguments are QuickCmdArg.
At the end you will either have an IO () (synchronous execution) or Cmd (which you can further use).
If a type implements this, you can pass it to mq.
