Top Forums Shell Programming and Scripting reverse search a text file from a specified line Post 302230044 by PacificWonder on Thursday 28th of August 2008 01:46:31 PM

I need to clarify step 3 and 5.

suppose I find pattern A on line 25 of the input text file, now I need to find the first occurence of pattern B from lines 25 through 1 of the file - in reverse. Say pattern B occurs on line 20 and line 15 and line 10. I need line 20, but not lines 15 & 10.

Thanks.
