Question

Create a file named script1.sh that contains a bash script that:

• Accepts NO command line arguments and does NOT use the read command. I will give you no credit if your bash script includes a read command. Also, you need to have at least one for..in loop in your code even if there may be other ways to do this problem.
• The script will go through a list of entries in the current directory (do not process subdirectories):
  • if the entry is a file and it is NOT executable, print out the file's content except for any lines that contain the string 'delete this' (case sensitive and NOT whole word only).
  • if the entry is a directory, then print the entry name and " is a directory" (see output for example)
  • if the file is your script, then print out the entry name and " is the script file!". HINT: You can do a comparison of the file name with $0 variable which is the name of the file being run.
