$8$ Create a simple shell script which will use environment variables to:

Read the TRGT$\_$EXT environment variablelto determine what file extension we are looking for $($for example, png$,$ txt$,$ pdf$,$ etc.$)$

When testing, set this environment variable up manually $($by physically typing commands into the command line$)$ before calling the script.

Set a new shell variable to the list of files in the current directory that have those extensions: $($use Is for this.$)$

In one single final echo statement, and then provide the following information:

The directory you are searching in $($current working directory$)$

a list of the files you found in step $2.$ Don't re$-$run the Is command, you should use the result saved in your environment variable from step $2.$

It's okay if the output looks wacky if there are no matching files.

Please help if you can, thanks
