Is it possible to run WSL Bash in non-interactive mode?

Question

One may want to use Bash on Windows in Task Scheduler or maybe as version-control hook scripts. Is it possible or supported?

Answer 1

If I'm understanding your question correctly, the -c option is what you're looking for. It allows you to directly invoke a Linux command.
For example, to open the man page for bash (perhaps in order to find out about the -c option):

bash -c "man bash"

Note: You can leave off the quotes if you escape any spaces (e.g. bash -c man\ bash), but it's often easier to just use the quotes, as the first unescaped space will lose the rest of your command.
e.g. bash -c man bash will be interpreted the same as bash -c man.
