I'm running PostgreSQL 8.3 with pl/python 8.3. I am getting a

results are the same whether I use os.popen or os.system. In
plpython, I run:
import os
cmd = 'ls -al /var/log/messages > /var/tmp/log'
x = os.popen(cmd)
for aline in x.readlines():
plpy.notice('aline = %s', aline)
and the contents of /var/tmp/log are "-rw-r----- 1 syslog adm 495523
Oct 30 11:52 /var/log/messages
When, within Python, I run:
>>> cmd = 'ls -al /var/log/messages > /var/tmp/log'
>>> x = os.popen(cmd)
>>> for aline in x.readlines():
... print aline
the contents of /var/tmp/log are "-rw-r----- 1 syslog adm 23591
2009-10-30 13:03 /var/log/messages
How, using plpython, can I get the output date/time in the same format
as when executing from within python itself?
Different locale settings will produce different formatting for the ls
command. For example...
[justinp@justinp /tmp/test]$ LANG=en_US.UTF-8 ls -l
total 0
-rw-rw-r-- 1 justinp justinp 0 2009-10-30 17:32 aa
-rw-rw-r-- 1 justinp justinp 0 2009-10-30 17:32 bb
-rw-rw-r-- 1 justinp justinp 0 2009-10-30 17:32 cc
[justinp@justinp /tmp/test]$ LANG=C ls -l
total 0
-rw-rw-r-- 1 justinp justinp 0 Oct 30 17:32 aa
-rw-rw-r-- 1 justinp justinp 0 Oct 30 17:32 bb
-rw-rw-r-- 1 justinp justinp 0 Oct 30 17:32 cc
It seems to me that you can just override the LANG variable directly in
your call to ls, since it's just running a shell command.
