that's not quite as portable as the other alternatives, though. "grep"
is at least available for non-Unix platforms, but "commands" requires a
unix shell.
for Python 2.5 and later, you could use:
def getoutput(cmd):
from subprocess import Popen, PIPE, STDOUT
p = Popen(cmd, stdout=PIPE, stderr=STDOUT,
shell=isinstance(cmd, basestring))
return p.communicate()[0]
print getoutput(["grep", pattern, glob.glob("*.txt")])
which, if given a list instead of a string, passes the arguments
right through to the underlying process, without going through the
shell (consider searching for "-" or ";rm" with the original code).
