Add a new line after a match

I would like to add a new line after a match. I know I can edit a file doing a perl -pi -e "s/(\d+)\s+\d+-\d\d\d\d)//g" filename which this would replace the phone number with something but can I add a newline after my phone number or how would I do this in a script? The file is huge.

here's part of the data I am looking at in my file:

N07Y O000000  1997000.00PSIN000.00P SI 01 (111) 111-11112005082200036424

perl -pi -e "s/(\d+)\s+\d+-\d\d\d\d\n)//g

... is this what you need?

Kind Regards

perl -pi -e "s/(\d+)\s+\d+-\d\d\d\d)/\n/g

Sort of, After the match of the phone number I want to add the new line so this wouldn't work because it would replace the phone number with new line:

perl -pi -e "s/(\d+)\s+\d+-\d\d\d\d)/\n/g"

Any other ideas?

sorry - your example confused me a bit as it explicitly replaces the phone number with nothing

how about this:-

perl -pi -e "s/(\d+)\s+\d+-\d\d\d\d)/$1\n/g

Kind Regards

all the above regexp have unmatched parenthesis in them, looks like none of them will work as posted.

Thank you Kevin - i am glad you are awake! I am a dumb ass... i trusted the regex supplied when i should have checked it



$_ = 'N07Y O000000  1997000.00PSIN000.00P SI 01 (111) 111-11112005082200036424';

s/^(.*) (\(\d{3}\) \d{3}-\d{4})(.*)$/$1$2\n$3/;



N07Y O000000  1997000.00PSIN000.00P SI 01(111) 111-1111

Kind Regards

or this way - focusing only on the phone number:-



$_ = 'N07Y O000000  1997000.00PSIN000.00P SI 01 (111) 111-11112005082200036424';

s/(\(\d{3}\) \d{3}-\d{4})(.*)$/$1\n$2/;

Hi spalmarez

Firstly: Your regex is syntactically incorrect due to the last bracket - a bracket on its own is a capturing and you are closing this... and there is no open bracket. This causes Perl to complain

Secondly: Your regex would work if there were no brackets in the phone number around the first 3 digits - as you have not catered for them in the regex

Kind Regards
