| # Coming from Bash | |
| If you're coming from `Git Bash` on Windows, then the external commands you're used to (bash, grep, etc) will not be available in `nu` by default (unless you had explicitly made them available in the Windows Path environment variable). | |
| To make these commands available in `nu` as well, add the following line to your `config.nu` with either `append` or `prepend`. | |
| ``` | |
| $env.Path = ($env.Path | prepend 'C:\Program Files\Git\usr\bin') | |
| ``` | |
| Note: this table assumes Nu 0.60.0 or later. | |
