could you please find a solution for this
script (called phone) that creates a simple telephone list (create an empty file called “phonlist” in home directory) . Each line in this file consist of two fields name and the phone number, the script should do the following:
When user types the command : “phone new <name> <number>” this will add new record (name,number) to the list.
When user type command: “phone <name>” then the script should search in the file “phonelist” and gets the phone number and display the result.
