Formatting an unformated “phone” number using sed.<\/figcaption><\/figure>\n\n\n\n

There may be a different and easier way to do this, but the main thing to learn here is the ^, $, and [[:digit:]] options.<\/p>\n\n\n\n

^ refers to the first part of a line
& which is our searched for pattern
$ refers to an end part of the line
[[:digit:]] searches for, you guessed it. Digits!<\/p>\n\n\n\n

The following command reads the incoming 10 digit number form echo and does the following.<\/p>\n\n\n\n

the ^<\/strong> tells it that the pattern needs to match at the beginning of the line
[[:digit:]]<\/strong> repeated tells it to search for three consecutive digits
(&)<\/strong> tells it to put brackets around the & which is our searched for pattern in the first part.
We then pipe that to another sed command which
searches for 4 consecutive digits
the $<\/strong> tells it that it needs to be at the end of the line.<\/p>\n\n\n\n

echo \"1234567890\" | sed -e 's\/^<\/strong>[[:digit:]][[:digit:]][[:digit:]]\/(&) \/g' | sed -e 's\/[[:digit:]][[:digit:]][[:digit:]][[:digit:]]$<\/strong>\/-&\/g'<\/pre>\n\n\n\n
Resulting output is<\/p>\n\n\n\n
(123) 456-7890<\/pre>\n\n\n\n
The following link was helpful while searching what the ^ and $ options do.<\/p>\n\n\n\n
