### Instructions
|
||
|
|
|
||
|
|
Create a script `env-format.sh`, which will print the environment variables that have the following formats:
|
||
|
|
|
||
|
|
- Print the `PWD` value.
|
||
|
|
- All the environment variables that have a letter `H` in the name, without printing the value of those variables.
