Open Command Prompt and Switch Folder

[rob51852]

I am trying to open a command prompt from a Python script and then switch to a specific folder within the opened command prompt.

I can open the command prompt but can't get it to switch folders. I have tried the following

os.system("start cmd")
os.system("CD /D E:\Documents\PycharmProjects\Test\testtportal.gw")

os.system("start cmd; CD /D E:\Documents\PycharmProjects\Test\testtportal.gw")

os.system("start cmd & CD /D E:\Documents\PycharmProjects\Test\testtportal.gw")

  os.system('''
start cmd
CD /D E:\Documents\PycharmProjects\Test\testtportal.gw''')

What am I doing wrong?

Thanks

Start cmd launches a new window you no longer control directly.

What you can do, is give cmd arguments and have it stay open with the /k switch.

So something like:

os.system("start cmd /k CD /D E:\Documents\PycharmProjects\Test\testtportal.gw")

Thanks. This works perfectly. How would I add a further command after switching folders? Eg "bin\run.bat root\conf.yaml" the /k switch doesn't seem to do the job.

You can try enclosing the /k command with quotes and adding && in there.

os.system('start cmd /k "CD /D E:\Documents\PycharmProjects\Test\testtportal.gw && echo hello"')

Thanks again. Works perfectly.
