The functiongetoptsiterates through all command line parameters, evaluating if they match an expected parameter set. It takes two arguments: a string representing allowed parameters and a variable name to use while iterating through arguments. Here’s an example that should explain things: 12345678910...
As on linux (and WSL) executables are started with an argument array, but on windows executables are started with a single CommandLine, bash.exe needs to split the given CommandLine into multiple arguments, that can be redirected to /bin/bash. As bash.exe is a Windows executable, in my ...

By using this approach, while being an unlikely use case, you can also debug Bash commands from the command line using the -c option. [me@linux ~]$ y=9 [me@linux ~]$ TRACE=1 BASH_ENV=my-debug-env bash -c "x=1; y=$y; echo \$((x+y))" Run TRACE mode [ DEBUG ]| BASH...
