Like grep -v for a string over 2 lines? Sed?
Hi,

I have a log file that I need to monitor as it's being written to, and I want to exclude certain strings from the output. At the moment I'm using ...

Code:
 tail -f LogFileName_`date +%d`.log | egrep -v "First String To Exclude | 2nd string | 3rd string"

...which works OK - but now I need to exclude another specific string and it's a string that is split over two lines.


Could anyone tell me how to do this please?


Thanks very much.

Edit to add ....

I'm sorry. I guess I should have posted this in "UNIX for Dummies".

Hammer & Screwdriver A couple of things
1) Might be easier to understand if we can see the file and what you are trying to select (not select) for.
2) grep (or egrep) can use a file. When you get start to have several options, put them all in a file (say called exclude) one to a line, then do your
Code:
egrep -vf exclude initial_file

Just a suggestion, as it may make your coding easier to read and maintain.
