Extracting block of text from log file

hattori.hanzo · 11-22-2010, 10:09 PM

I have a log file and want to extract all blocks of text that start with START and ends with END. Each block is 5 lines.

Code:

--- START

blah blah blah

--- END

I was thinking of :

Code:

grep -A 5 "--- START" file

What would I use if each block was 'not' 5 lines?

Thanks & Regards

Use sed - you can use the START and END as address range delimeters.
For simple requirements does the job fine.
