how to create a path alias?

So "cs" will be map开发者_开发百科ped to "/College/" so that I can run the command "cd cs"?

I believe you are asking about how to create a symbolic link (or symlink) like:

ln -s College cs

Although, there are other ways to speed up your workflow, such as setting the CDPATH:

export CDPATH=.:~/:/College/

Or you could even make "cs" an alias that will perform the action "cd /College/":

alias cs='cd /College/'

If you did the above, you would type cs instead of cd cs to get there.
