Write a Borne Again shell $($BASH$)$ script which receives a path as the input and calculates the number of each file type defined in Linux$/$Unix file types in the given path. Name the script $$filestatics$.$ Here are some sample runs of the $$filestatics$$:

filestatics

You must enter a path:

Usage: filestatics pathname

filestatics foodir

foodir not found!

filestatics $/$dev $/$etc

You must enter a path:

Usage: filestatics pathname

filestatics $/$dev

Here is the $/$dev$$ directory file type statistics:

$$Ordinary$$Block$$character$$directory$$link$$pipe$$socket$$

$5101361000$

filestatics $/$etc

Here is the $/$etc$$ directory file type statistics:

$$Ordinary$$Block$$character$$directory$$link$$pipe$$socket$$

$150320715$

Note that the above numbers might be different in your machine.

Bonus

You will receive $2\%$ bonus mark, if you also print the statistics for permission bits as well. Here is a sample output:

filestatics $/$dev

Here is the $/$dev$$ directory file type statistics:

$$Ordinary$$Block$$character$$directory$$link$$pipe$$socket$$

$5101361000$

Here is the $/$dev$$ directory permission statistics:

$$owner$$Group$$Others$$

r w x r w x r w x

$1083872420$

Always check if the script has received the correct number of parameters and their orders based on the shown examples. If the user enters wrong parameter print an error message and notify the right usage format. In case of usage error or any other unusual error you need to exit with none zero value.

The output of your script should be nicely formatted. Use the tab character to properly format the output of your script.

If you create intermediate temporary files anywhere including in $/$tmp$,$ remove them before your script ends.

Make sure, you have had enough comments to make your script readable and understandable. Also: $($Don$\text{'}$t use the "awk" command or any others like it$)$
