Top Forums Shell Programming and Scripting [Awk] Extract block of with a particular pattern Post 302496648 by alister on Monday 14th of February 2011 08:07:38 PM

A couple of things to keep in mind, in case the solutions don't work for the OP:

1. The use of a regular expression or string in RS is a gawk extension.
2. Since at least one field is free text, it's probably a good idea to anchor the FS regular expression.

NAME
ausearch_add_regex - use regular expression search rule SYNOPSIS
#include <auparse.h> int ausearch_add_regex(auparse_state_t *au, const char *expr); DESCRIPTION
ausearch_add_regex adds one search condition based on regular expressions to the audit search API. The search conditions can then be used to scan logs, files, or buffers for something of interest. You may not use this in combination with any other search expression. The regu- lar expression follows the posix regular expression conventions. The search results are at the record level and not the field. RETURN VALUE
Returns -1 if an error occurs; otherwise, 0 for success. SEE ALSO
