I'm using subprocess.Popen with Python, and I haven't come across an elegant solution for joining commands (i.e.
I've read a bunch of examples but none of them work for this specific task.
Python code:
x = Popen(commands, stdout=PIPE, stderr=PIPE, shell=True)
print commands
stdout = x.stdout.read()
stderr = x.stderr.read()
print stdout, stderr
return stdout
Output:
[user@host]$ python helpers.py
['ssh', '-t', 'user@host', ' ', "'service --status-all'"]
usage: ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_ad
Following is the code:
import subprocess
import re
#stores partitions from df command in df_partition list
p = subprocess.Popen("df -h", stdout=subprocess.PIPE, shell=True)
dfdata, _ = p.communicate()
dfdata = dfdata.replace("Mounted on", "")
columns = [list() for i in range(10)]
for line in dfdata.split("\n"):
line = re.sub(" +", " ", line)
for i,l in enumerate(line.split("
I'm trying to run an scp (secure copy) command using subprocess.Popen.
I have a UI that upon event should POST to a script on that server.
I have the following Python script, chmod +x'd.
Hi all...
I need my PC to auto turn on every day at 9:00 AM.
To make it auto turn on i've done the following:
1) Enabled [Resume By Alarm] in BIOS and set alarm to 9:00
2) Changed SYSTOHC to "no" in /etc/sysconfig/clock
3) Edited my halt.local to run a special script before shutdown. The script contains:
i'm trying to run:
# if so, kill the atms and restart it
try:
with open(os.devnull, 'w') as devnull:
call(["/usr/sbin/atms","-k"], stdout=devnull, stderr=devnull)
except Exception, e:
print the error
and I get
"'Popen' object has no attribute '_child_created'" in <bound method Popen.__del__ of <subprocess.Popen object at 0x1373790>> ignored
What does it mean?

I have a memory intensive Python application (between hundreds of MB to several GB).
I have a couple of VERY SMALL Linux executables the main application needs to run, e.g.
child = Popen("make html", cwd = r'../../docs', stdout = PIPE, shell = True)
child.wait()
When I run these external utilities (once, at the end of the long main process run) using subprocess.Popen I sometimes get OSError: [E
