How to add man and zip to "git bash" installation on Windows

7-zip can be added to gitbash as follows:

1. Install 7-zip on windows.
2. add 7-zip folder (C:\Program Files\7-Zip) to PATH
   On gitbash exp: export PATH=$PATH:"C:\Program Files\7-Zip" (temporary)
   On Windows, adding PATH like image below (permanent)
   

3. duplicate a copy of 7z.exe to be zip.exe
4. reopen gitbash again. done!

This way, it works on my laptop.

If you skip step 3. you still can call zip command as 7z instead of zip

Conclusion: Gitbash is running base on windows Path, I think you can run any command that you have added to your Windows PATH.

Here's another, slightly different, set of instructions to install zip for git bash on windows:

1. Navigate to this sourceforge page
2. Download zip-3.0-bin.zip
3. In the zipped file, in the bin folder, find the file zip.exe.
4. Extract the file zip.exe to your mingw64 bin folder (for me: C:\Program Files\Git\mingw64\bin)
5. Navigate to to this sourceforge page
6. Download bzip2-1.0.5-bin.zip
7. In the zipped file, in the bin folder, find the file bzip2.dll
8. Extract bzip2.dll to your mingw64\bin folder (same folder as above: C:\Program Files\Git\mingw64\bin)
