pysyscmd 1.0.0

Description:

pysyscmd 1.0.0

Utility to call any system command from python.
Import any program that’s on your PATH from syscmd.cmds and you’ll get a
function that executes the program with the given positional arguments. By,
default, the function uses subprocess.check_call to execute the program. But
this can be changed by passing in one of syscmd.CALL, syscmd.CHECK_CALL,
or syscmd.CHECK_OUTPUT as the f argument to your function to get the
respective subprocess function. Expect the same behavior from the imported
syscmd functions as the subprocess functions, eg. return value, standard
in/out/error, etc.
In addition to the positional arguments and f, the imported functions also
accept all the keyword arguments of the underlying subprocess functions.
Examples:
# Import various system commands
>>> from syscmd.cmds import echo, ls, true, false

# Run 'echo' with three positional arguments; stdout goes to stdout and the
# exit code is returned
>>> res = echo('one', 'two', 'three')
one two three
>>> print res
0

# Run 'ls' with no arguments
>>> res = ls()

# Run 'false'
>>> res = false()

subprocess.CalledProcessError: Command '('/usr/bin/false',)' returned non-zero exit status 1

# Uh-oh... a non-zero exit code raises an exception because it's run with
# 'subprocess.check_call'

# Import CALL from syscmd
>>> from syscmd import CALL
>>> res = false(f=CALL)

# Now running 'false' doesn't cause an exception, but we still get the exit
# code as the return value
>>> print res
