Better split the arguments beforehand: cmd = ["gawk", "-f", "altertime.awk", "-v", "time_offset=4", "-v", "outfile=testdat.sco", "i1.sco"] Now, what do you want to do with the output? Do I need to do something or can I do something to put an end of line charecter in the output?? check over here

There, you'll find a block starting with if shell: that will search the environment for said variable and use it to create the arguments used to launch the process. http://amigasuperbit.com/cannot-find/pkgmgr-the-system-cannot-find-the-file-specified.html However, shell=True can be a security risk if you're passing arguments that may come from outside your program.
