A fast subprocess library
Note
This library is no longer maintained.
Modern versions of subprocess are very close to as fast as this library, so just use that :)
Spawning a process with fastprocess is very easy
In [1]: from fastprocess import FastProcess
In [2]: pid = FastProcess(['echo', 'hello', 'world'])
hello world
In [3]: pid.wait()
Out[3]: 0
You can redirect io using the stdin, stdout, and stderr options
In [4]: null = open('/dev/null', 'w')
In [5]: pid = FastProcess(['yes'], stdout=null)
In [6]: pid.terminate()
terminate():
Sends SIGTERM to the process
kill(sig):
Sends signal 'sig' to the process
wait():
Waits for the process to exit then returns the exit code
