Need help to use regex to do search and replace. Don't know how to and can't figure out how :(
Hi,
Below is an excerpt from a 20000+ lines and I want to do a search and replace of a specific string but I don't know how and I can't figure out how to. Can't find an example from Google or anywhere to do what I am wanting to do.
I need to search for all lines that contain the string /db/LTS/abcp_ but only those that ends in .dbf. So from the excerpts above, it should find the line below:
And I want to replace them so it so that it will be
So, basically I need to change /db/LTS/abcp_ to /db/LTS/abct_. It is the one in BOLD that I am wanting to search and replace.
The grep regex below seems to do what I wanted. But I don't know how to do like a sed search and replace thing
Any help will be much appreciated.
P.S.:
- Is there any way to colorize or highlight certain text? I was hoping to be able to do that in this post but can't find the option to do so. I thought that option was available on the older forum ???

Hi,
I'm trying to match the front and back of a sequence. It works when there is an exact match (obviously), but I need the regex to be more flexible. When we get strings of nucleotides sometimes their prefixes and suffixes aren't exact matches. Sometimes there will be an extra letter and... (2 Replies)

ausearch_add_timestamp_item
AUSEARCH_ADD_TIMESTAMP_ITEM(3) Linux Audit API AUSEARCH_ADD_TIMESTAMP_ITEM(3)NAME
ausearch_add_timestamp_item - build up search rule
SYNOPSIS
#include <auparse.h>
int ausearch_add_timestamp_item(auparse_state_t *au, const char *op, time_t sec, unsigned milli, ausearch_rule_t how)
DESCRIPTION
ausearch_add_timestamp_item adds an event time condition to the current audit search expression. The search conditions can then be used to
scan logs, files, or buffers for something of interest. The op parameter specifies the desired comparison. Legal op values are <, <=, >=, >
and =. The left operand of the comparison operator is the timestamp of the examined event, the right operand is specified by the sec and
milli parameters.
The how value determines how this search condition will affect the existing search expression if one is already defined. The possible val-
ues are:
AUSEARCH_RULE_CLEAR
Clear the current search expression, if any, and use only this search condition.
AUSEARCH_RULE_OR
If a search expression E is already configured, replace it by (E || this_search_condition).
AUSEARCH_RULE_AND
If a search expression E is already configured, replace it by (E && this_search_condition).
RETURN VALUE
Returns -1 if an error occurs; otherwise, 0 for success.
APPLICATION USAGE
Use ausearch_add_item(3) and ausearch_add_interpreted_item(3) to add conditions that check audit record fields. Use ausearch_add_expres-
sion(3) to add complex search expressions using a single function call.
SEE ALSO ausearch_add_expression(3), ausearch_add_item(3), ausearch_add_interpreted_item(3), ausearch_add_regex(3), ausearch_set_stop(3), ause-
