In Linux OS, you have a directory named “mydata” which contains a few files with different types of extensions. Also, there is a file named “sample.txt”.

Solution

The best suitable commands to get the above-mentioned outputs considering the range as b to m are:

  1. To get the type of each file that is present in the directory whose file name starts with any alphabet in the specified range:
file /mydata/[b-m]*
  1. To get the type of given file:
file sample.txt
  1. To get the extensions of all files:
file /mydata/*

So, the correct option is:

file /mydata/[b-m]*

file sample.txt

file /mydata/*

This problem has been solved
