Hi folks,
I've been pondering how to get python to read from a pipe outside of
itself, sort of.
For example I tried a simple python prog to do a grep, eg
# ps -e | myprog.py cron
would give this output
3778 ? 00:00:00 crond
same as
# ps -e | grep cron
The way I did this was to use sys.stdin.readlines() to get the output
from the pipe.
Here is the program:
[code]
import sys, glob
args = sys.stdin.readlines() # found on the net
pat = sys.argv[1]
for i in args:
if (i.find(pat) != -1):
print i,
[/code]
My question is am I getting the output from the pipe in the correct
way ? The way Im doing it works (so far) but should I be doing it
another way ?
Many thanks
Nick .
