|
||||||
## Usage
|
|
||||||
|
|
||||||
`loadenv` loads the environment file provided via `-f` into the environment and runs the command provided after the arguments.
|
|
||||||
If no file is provided, `.env` is used by default.
|
|
||||||
If no command is provided, `loadenv` prints all environment variables to stdout.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
The variables will only be available to the given command. They will be deleted after the command exits.
|
|
||||||
`loadenv` can be useful when working with programs which heavily use environment variables.
|
|
||||||
|
|
||||||
```sh
|
|
||||||
$ cat .env
|
|
||||||
# production server configuration
|
|
||||||
DATABASE_HOST=prod-server.com
|
|
||||||
DATABASE_USER=milarin
|
|
||||||
DATABASE_PASS=my-super-secure-password
|
|
||||||
|
|
||||||
$ # show the 3 last added env variables
|
|
||||||
$ loadenv | tail -n 3
|
|
||||||
DATABASE_HOST=prod-server.com
|
|
||||||
DATABASE_USER=milarin
|
|
||||||
DATABASE_PASS=my-super-secure-password
|
|
||||||
|
|
||||||
$ cat dev.env
|
|
||||||
# development server configuration
|
|
||||||
DATABASE_HOST=dev-server.com
|
|
||||||
DATABASE_USER=milarin
|
|
||||||
DATABASE_PASS=my-super-secure-password
|
|
||||||
|
|
||||||
$ # load dev.env into environment and run the command env. show last 3 lines
|
|
||||||
$ loadenv -f dev.env env | tail -n 3
|
|
||||||
DATABASE_HOST=dev-server.com
|
|
||||||
DATABASE_USER=milarin
|
|
||||||
DATABASE_PASS=my-super-secure-password
|
|
||||||
```
|
|
||||||
|
|
||||||
environment variables in that file will be expanded:
|
|
||||||
|
|
||||||
```sh
|
|
||||||
$ env | grep USER # current value of $USER
|
|
||||||
USER=milarin
|
|
||||||
|
|
||||||
$ cat .env
|
|
||||||
# expand $USER reference
|
|
||||||
USERNAME=$USER
|
|
||||||
|
|
||||||
$ loadenv | tail -n 1
|
|
||||||
USERNAME=milarin
|
|
||||||
```
