- Comprueba si la variable especificada tiene un valor [n]o-vacío:

`[ -n "${{variable}}" ]`

- Comprueba si la variable especificada tiene un valor vacío:

`[ -z "${{variable}}" ]`

- Comprueba si el archivo ([f]ile) especificado existe:

`[ -f {{ruta/al/archivo}} ]`

- Comprueba si existe el [d]irectorio especificado:

`[ -d {{ruta/al/directorio}} ]`
