Shell Programming and Scripting

Hi All
I have a file which contains the timestamp of the log and a message and I want to implement a polling mechanism, where this log file is pooled every 2 minutes and list the errors in the file. I want to list down the errors only after the timestamp in the file is more than the current timestamp.
Example :-
File <randomcheck.log>

Code:

2018-07-16 10:56:21,174 [info - we are in the team]
2018-07-16 10:56:21,181 [Error - we are not in the team - access denied]
2018-07-16 11:01:18,522 [info - we are in the team]
2018-07-16 11:01:19,522 [info - we are in the team]
2018-07-16 11:01:20,548 [info - we are in the team]
2018-07-16 11:01:21,548 [info - we are in the team]
2018-07-16 11:01:22,548 [Error - we are not in the team - access denied]
2018-07-16 11:01:23,548 [info - we are in the team]
2018-07-16 11:01:23,548 [info - we are in the team]
2018-07-16 11:01:23,549 [info - we are in the team]

Lets say, I execute the check job at 2018-07-16 11:00:00
Expected output :-
2018-07-16 11:01:22,548 [Error - we are not in the team - access denied]

I do not want to have any earlier message displayed.

Can not use grep as the logs are random, they are not written every second/ minute so can not create a pattern.


Appreciate your help on this.

I'm afraid clairvoyance can't be programmed with today's logics and languages. How do you expect a job run at 11:00:00h to print a message that will come in at 11:01:22,548?


EDIT: Apart from the esoteric aspect, any attempts, ideas, thoughts from your side?

Hi Rudic, thanks for the reply. May be I was not clear enough.
The log file has the timestamp in it.
I will pass the from-time in the check job and it should sweep the log file after that from-time based on the timestamp in the file and give me errors
