WRITE IN BASH $($using LINUX$).$ Thank you.

Create a text file called phoneno.txt with the following content. I highlighted the first $5$

lines to show that they follow the convention of a phone number.

$(123)456-7890$

$123-456-7890$

$1234567890$

$456-7890$

$4567890$

$(123)-456-7890$

$1234-5678$

$1234567890123$

$1234567890$

Come up with your regex pattern so that the following command outputs only the first $5$

lines of phoneno.txt:

$ grep $-$E "your$\_$pattern$\_$here" phoneno.txt
