I have been developing a tool that is designed to execute a series of commands.
These commands are written as if they were being entered into a terminal or console. In order to achieve this, I have utilized Popen() with the parameter shell=True to replicate the process of typing in a terminal or console.
Now, I am interested in giving the user the ability to specify their preferred command interpreter. Specifically, on Windows, users can opt to use "Git bash" instead of cmd.exe.
As stated in the documentation for Popen(), the choice of interpreter can be determined by setting the environment variable COMSPEC.
While attempting to set COMSPEC to
C:\Program Files (x86)\Git\bin\bash.exe/c to the command, whereas base expects -c.
I have contemplated removing the use of shell=True, but I am uncertain about the differences involved:
- Should I use
.split()to separate the command line into arguments? If so, how should it be done? - Are there any specific flags that are implied by or set when using
shell=True?
The objective here is to avoid reinventing the features present within Popen(shell=True) while still closely replicating its functionality.
Do you have any insights or suggestions to offer?
