shell script find a line and the next line (grep?)
 
Lets say I have the following text file

Code:
name
john123

phone:
123-213-4566

name
chris035

phone:
236-555-6546

name
bob56

phone:
333-666-9852
is there a way to find all the line that have "phone" and print them and the next line to make the out put look like this:
Code:
phone:
123-213-4566
phone:
236-555-6546
phone:
333-666-9852
I've looked into using grep awk & sed

I'm sure there is a way but I have yet to find it.

grep -A1 phone $file


This only works with GNU grep. Normal grep doesn't have -A (after) option ( see also -B => before)

Awk

Awk can handle multiline records by specifying the field separator to be a newline and set the record separator to an empty string.

Here's an example using sed.
Code:
sed -n '/phone/,+1 p' file.txt
