UNIX for Dummies Questions & Answers

Hi,

I have to handle multiple projects at same time. And i have to go to a folder often in each project. So I have a alias to there.

Lets say i am in project environment "sky"
(pwd = /home/sky/sim/bla/).
For this project i have stored the scripts in the folder lets say "/home/sky/dog/script". For this project I have alias "sgo" to go to script folder

Now I am in another project environment "earth".
(pwd = /home/earth/sim/bla/dog/exec/).
For this project i have stored the scripts in the folder lets say "/home/earth/tiger/pro/script". For this project I have alias "ego" to go to script folder

As you see I have different alias for each project environment. Now I have too many project and it gets really complex for aliases.

Is there anyway that I have just one alias(lets say just "go") and it responds differently based on current directory?

Thanks in advance!

Not just an alias, but a sourced script in your path could also extract the project name for $PWD and add the script dir to the head of the $PATH. You could even build this into your ~/.profile or the like.

What's your shell?

An alias probably couldn't do it, but a function probably could, if your shell supports them.

Code:

go() {
        case "$PWD" in
        /home/earth/sim/bla/dog/exec/) earth_stuff ;;
        /home/sky/dog/script) sky_stuff ;;
        *) echo "Unknown folder $PWD" >&2 ;;
        esac
}

Well, an alias can be a function! I am more into a bin dir of scripts, so I can $PATH into my tools on any id, copy the tools to other hosts easily, and keep .profile on a diet. Go could be a script that starts a temporary child shell with $PATH appropriate to the $PWD. You can exit it when done there (or pile them up).
