# Where is my sage?

My computer is Windows-based, so I used WSL (Ubuntu 22.04) to compile Sage 10.0 from source code. I followed the instructions from the link below. It took me approximately 5 hours.

It indicates that the installation was successful.

However, it can only run sage within the Sage directory.

So I executed the following command, but after executing it, I can no longer find the Sage directory.

```
sudo ln -sf $(pwd)/sage /usr/local/bin
```

I don't know what happened. I reopened WSL and I don't know where to find my Sage again. The Sage directory is missing!

How can I find my Sage installation directory again and run it? It would be frustrating to recompile it again.

A possible solutions is to set up

`SAGE_ROOT`

variable like:@Max Alekseyev It gives me that

`-bash: export:`

=': not a valid identifier -bash: export:`/home/user/sage/sage': not a valid identifier`

Indeed, I'm not quite sure how to find my Sage executable file. I can't even find sage/sage directory. I assure you I haven't done anything other than running the command

`sudo ln -sf $(pwd)/sage /usr/local/bin`

in that link. The Sage directory is missing ( was deleted or hidden?)My bad - there should be no spaces around

`=`

:Your screenshot shows that

`sage/sage`

directory is located in the home directory of user`zlc`
