Search for a pattern from the result of search - Shell Programming and Scripting

boopathi_d · #1 12-05-2007

I want to search for a pattern in a file based on the result of search. For example,

grep '05-Dec' filename.ext

For searching 'Exception' pattern, I used,

grep 'Exception' filename.ext

Anyway, these two worked successfully when run individually. But I want to search the second pattern based on the result of the first pattern.

Please help me out.

U have to understand the use of pipes:

Code:

grep '05-Dec' filename.ext|grep 'Exception'

Code:

awk '/05-Dec/ && /Exception/{print}' file

That´s better, just a minor thing u can drop print

:

Code:

awk '/05-Dec/ && /Exception/' file
