backslash in command run

[Challans Town Hall]

Good morning,

I'm trying to run a command in the pyton.py file, but each time my backslashes are doubled and the command fails.
The same problem persists, c:\ is interpreted as c:\\.

The command to execute is:

Code: Select all

powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\

Code: Select all

run(r'powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\')

Code: Select all

run(r'"powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\"')

Or

Code: Select all

commandsm=r"powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\"
run(commandsm)

All these commands return the following to me:

Code: Select all

2016-09-13 11:58:29,858 CRITICAL Fatal error in install script: CalledProcessError: Command '('"powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\\ -verbose"',)' returned non-zero exit status 1:Traceback (most recent call last):

How can I keep the "c:\" character intact in the run command?

THANKS.

Good morning,

Have you tried using the escape character \? (c:\\)

Code: Select all

commandsm=r'powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath c:\\'

Hello,

yes, and so it looks like this: c:////
(all backslashes are doubled)

Good morning,

I don't know if this is the best way to do it, but using the following code should work.

Code: Select all

command = r"powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath "
path = os.path.normpath('C:\\')
commandsm = ''.join([command,path])
run(commandsm)

Thank you, this solution works!
