git commit error: pathspec 'commit' did not match any file(s) known to git
The command line arguments are separated by space. If you want provide an argument with a space in it, you should quote it. So use git commit -m "initial commit".
I would just like to add--
In windows the commit message should be in double quotes (git commit -m "initial commit" instead of git commit -m 'initial commit'), as I spent about an hour, just to figure out that single quote is not working in windows.
