Question

I’m trying to execute the following code but it is not working

    p = subprocess.Popen("ssh root@IP cd /opt/msys/pe2/bin;./perlscript.pl; -a file.csv", 
                shell=True,stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

   OR:
   p = subprocess.Popen("ssh root@IP /opt/msys/pe2/bin/perlscript.pl; -a file.csv", 
                shell=True,stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

The problem with the first is i can seem to chain together commands after ssh. The 2nd is if i call the file directly the -a arg can’t find that file because im not in that directory. I was hoping to use the cwd parameter to Popen, but it fails because I’m not ssh’d into the server.

Try quoting the command being sent to ssh:

subprocess.Popen('ssh root@IP "cd /opt/msys/pe2/bin;./perlscript.pl;" -a file.csv'

Otherwise you’re telling the local shell to do it.
