Command line

[amfr]

Hoe would I call something on the command line from python, e.g. "ls
-la"?

Re: Command line

What OS are you using. I'm not sure about anything else but on a mac
it's:
[color=blue][color=green]
>>import os
>>os.system(" ls -la")[/color][/color]

Use the module subprocess - otherwise maybe popen2 or os.

os.system(cmd), or some relative:

http://docs.python.org/lib/os-process.html

http://docs.python.org/lib/os-newstreams.html#os-newstreams

or

http://docs.python.org/lib/module-subprocess.html

:::

also note that you shouldn't use external commands for trivial things like
getting a list of files or getting the size of a file; you can get a list of all
files in a directory with

files = os.listdir(dire ctory)
for file in files:
file = os.path.join(di rectory, file) # full path
...

or

files = glob.glob(patte rn)
for file in files:
...

and you can get information about a given file with

st = os.stat(file)

size = st.st_size
mtime = st.st_mtime
(etc)

or

size = os.path.getsize (file)
mtime = os.path.getmtim e(file)
(etc)

Worthwhile as oldbies too ;-)
