guys I truly need the solution of this, with some explanation ! 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. and what does these commands do: [[ -z $user ]] -- grep -- -eq 1 0 -- [[ `grep -c $user` -eq 1 ]] -- thanks
I don't have a solution ready for you, but you can read through this guide: http://tldp.org/LDP/abs/html/ Afterwards you'll be a bash scripting genius.
thank you, but I really need a solution for that script, I must read and learn to do my tasks but I am a bignner on it and dont have time, so please forgive me
The first tests if $user veriable is empty, The second is invalid The third tests if the number of characters in $user variable has more one character. And finally i will write you a quick script when i have some time on my hands
