Write a bash script file that tests each file entry in thecurrent directory. It should determine if it is a file ordirectory. If it is a file, it will determine if it is readable ornot. If it is readable, it will display only the first 4 lines tothe terminal in sorted order (just sort the first 4 lines).
If it is a directory, it should display the contents of thatdirectory (the files and subdirectories).
NOTE: Please don’t use the read command or arguments with yourscript. Note that you don’t need to use either one of these methodsto get a list of files in the current directory.
=====================================
Example Output
Note that the output
from running the script starts at
the sixth line
