erlcmd

Erlcmd includes a simple tool function cmd:run. It likes os:cmd but returns exit status code and stdio output.

How to use

Download src/cmd.erl to your local disk then run:

Exe = os:find_executable("ls"),
CmdLine = Exe ++ " -a ./src",
{ok, ExitStatus, Output} = cmd:run(CmdLine, 1000),
io:format("exit status code: ~p~noutput: ~n~s", [ExitStatus, Output]).

Or like this:

Exe = os:find_executable("ls"),
{ok, ExitStatus, Output} = cmd:run(Exe, ["-a", "./src"], 5000), 
io:format("exit status code: ~p~noutput: ~n~s", [ExitStatus, Output]).
