Top Forums UNIX for Dummies Questions & Answers Lines of code in egrep question Post 302932576 by Corona688 on Thursday 22nd of January 2015 03:10:39 PM

First off, your regex is a little strange. "$2015-01-22" is nonsensical because $ means "match the end of the line", and there's nothing after the end of the line. Did you mean ^, "match the beginning of the line"? It will also take your spaces literally, so "(...) | (...)" means "match this block and a space, or match a space then this block".

But anyways, grep can't can't remember what happened in past lines. It's not a programming language.

awk can remember what's happened in past lines, because it is.

Code:
awk '/2015-01-22.*NS Primary Error/ { A=1 } /NS Primary Error.*2015-01-22/ { B=1 } END { exit(!(A && B)); }' inputfile

If it finds lines matching "2015-01-22.*NS Primary Error" it sets the variable A true. If it finds lines matching "NS Primary Error.*2015-01-22" it sets the variable B true. If, once all lines are read, both A and B are true, it returns 0(i.e. success), otherwise returns 1 (failure) to the shell.
