A command. You can execute this with run' or run.

Make a Cmd from the path to an executable. Does not take PATH into account. See makeCmd for a version that provides some sensible defaults, like forwarding stdin, stdout, stderr.

Pass an argument to the command.

Embeds the IO action inside the command, such that the IO action is executed when the command is executed.

Executes some code after launching the process. If launching the process fails, it will be provided with the exception it failed with.

Runs the specified command asynchronously and returns the process status.

Runs the specified commands and replaces the current process with it. This will not return unless an error occurs while executing the process.

Bind a fd in the new process to a fd available now. If you try to bind an fd already bound, it will simply replace the older binding.

Pass an argument of the form /proc/self/fd/<n> to the process, where n is an fd which is a duplicate of the fd provided here.

Don't open a fd in the new process if it was going to be opened by passFd. Does not affect fds opened by passArgFd.
