Cygwin - Obtaining new commands - Edit

Question

I installed Cygwin to get the bash shell on window 8, and I'm not able to use vim, ssh, apt, install command. Many commands work now, while it didn't work in few minutes ago. What could I do to obtain those new command with Cygwin?

EDIT :

I know now I have to install apt-cyg using this website. This is exactly what I did, but even if the "apt-cyg file" is in the Downloads directory, I still don't know how to use this file to make it work.

Answer 1

by default cygwin setup install only the packages in the Base category. If you need to install other packages you need to select them.

https://cygwin.com/cygwin-ug-net/setup-net.html#setup-packages

To search which package contains what you are looking for, you can use the web search
https://cygwin.com/cgi-bin2/package-grep.cgi

or the command line one

cygcheck -p "file_name"

Answer 2

I still don't know how to use this file to make it work.

Please read the apt-cyg readme, it tells you everything you need to know:
