| # fx use |
| |
| re-use a previous build directory set up by `fx set` |
| |
| ```none |
| usage: fx use DIR |
| or: fx --dir DIR use |
| or: fx use |
| |
| Switches further `fx` commands to using a different build directory. |
| This only works if `fx --dir DIR set ...` succeeded previously |
| (and DIR has not been removed since). The next `fx build` or other |
| such command will now refer to DIR. The previous build directory is |
| left in place, so you can switch back again with `fx use` later. |
| |
| fx use without arguments will list the available build directories, naming |
| the current active build directory (if any). |
