The directory ~/class/e01/q05 contains four files: in1.html, in2.html, in3.html and in4.html

To complete this question, create a file q05.sh that when sourced (as in source q05.sh) will execute the appropriate Linux commands to do the following:

1. Create a file named hrefs.txt that contains all the lines from the four files above that contain the string href (independent of case).

2. Create a file named pics.txt that contains all the lines from the above four files that contain either jpg, jpeg or gif file (again independent of case).

3. Display the number of lines in hrefs.txt (Im looking for an output line containing a single number)

4. Display the number of lines in pics.txt (Im looking for an output line containing a single number)

5. Display the number of gif files found in the four files above (again, just a number).
