# osenv
|
||||||
|
|
||||||
|
Apply .env files to shell environments!
|
||||||
|
|
||||||
|
## What is it
|
||||||
|
|
||||||
|
Given a .env like this:
|
||||||
|
|
||||||
|
```env
|
||||||
|
DB_USER=admin
|
||||||
|
DB_PASSWORD=changeme
|
||||||
|
```
|
||||||
|
|
||||||
|
it will generate scripts for bash (and likely other *sh) and powershell, like:
|
||||||
|
|
||||||
|
### Powershell
|
||||||
|
|
||||||
|
Example output:
|
||||||
|
|
||||||
|
```ps1
|
||||||
|
$env:DB_USER = "admin"; $env:DB_PASSWORD = "changeme"
|
||||||
|
```
|
||||||
|
|
||||||
|
Use `osenv` like this:
|
||||||
|
|
||||||
|
```ps1
|
||||||
|
osenv -s ps1 | iex
|
||||||
|
```
|
||||||
|
|
||||||
|
### *nix shell
|
||||||
|
|
||||||
|
Example output:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
export DB_USER=admin
|
||||||
|
export DB_PASSWORD=changeme
|
||||||
|
```
|
||||||
|
|
||||||
|
Run `osenv` like this:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
eval $(osenv)
|
||||||
|
```
