Script to format phone numbers

Noob here, I need help with a shell script. I need to remove hyphens and add opening parenthesizes around the area code. I am able to show just the area code by adding echo {phone:0:3} to the script. Any help is much appreciated.

Write a script (called phone_num.sh) that prompts users for a phone number is this format xxx-xxx-xxxx

• convert it to (xxx) xxx-xxx

• convert it to xxxxxxxxx

Example If the input is 123-123-1234, your code would display

(123) 123-1234

1231231234

echo "Please enter phone number in the following format xxx-xxx-xxxx:" read phone echo ${phone:0:3} 

This will give me the area code, which I'm not looking for. I need hyphens removed and parenthesizes added to the area code.

Maybe these variable assignments might help you out:

$ phonedash=123-123-1234 $ phonenodash="${phonedash//-}" $ phone=$phonenodash $ echo $phone 1231231234 $ echo "(${phone:0:3}) ${phone:3:3}-${phone:6:4}" (123) 123-1234 $ new_phone=$(echo "(${phone:0:3}) ${phone:3:3}-${phone:6:4}") $ echo $new_phone (123) 123-1234 

Bash + printf

$ VAR="123-456-7890"; printf "( %s ) %s - %s \n %s%s%s\n" ${VAR:0:3} ${VAR:4:3} ${VAR:8:4} ${VAR:0:3} ${VAR:4:3} ${VAR:8:4} ( 123 ) 456 - 7890 1234567890 

sed

$ phone="123-456-7890" $ plainPhone=$(echo $phone | sed "s/-//g") $ formatedPhone1=$(echo $phone | sed "s/\(.*\)-\(.*\)-\(.*\)/(\1) \2 - \3/") $ formatedPhone2=$(echo $plainPhone | sed "s/\([0-9]\{3\}\)\([0-9]\{3\}\)\([0-9]*\)/(\1) \2 - \3/") $ $ echo $plainPhone 1234567890 $ echo $formatedPhone1 (123) 456 - 7890 $ echo $formatedPhone2 (123) 456 - 7890
