Question

I want to extract from SVN log all text between the lines. If it is with sed, awk or grep it’s better.

Example: svn.log

   M /trunk/apps/test.php

Changed paths:

Ticket #1089: translation update: send to friend form
http://example.com/projects/147/tickets/1089

I want to search for Ticket #1000 and retrieve entire block between the lines

Thanks in advance.

Answer 1

this awk oneliner gives you the output you need:

awk -vRS='-+\n' '/Ticket #1000/' svn.log

test

kent$  awk -vRS='-+\n' '/Ticket #1000/' svn.log

You have seen that the line separator (—–) was not in output. it could be easily added if you really need.
