Writing into log file - Scripting

Archana1 — Sat, 17 Apr 2010 19:05:46 GMT

Hello Experts,

Please help me simple scripting -

which captures ERROR,WARN,FATAL entries between 6 AM - 6PM (Monday - Friday) and should put in seperate log file.

Here is my log file :-
2010-03-30T16:12:42,728 ERROR [00000008] :sassrv - ERROR: Failed to retrieve log
in credential from the authentication domain.
2010-03-30T16:12:42,728 ERROR [00000008] :sassrv - ERROR: Failed to retrieve log
in credential from the authentication domain.

Hi:

You could use:

# cat ./filter
#!/usr/bin/perl
use strict;
use warnings;
while (<>) {
next unless m{(?:ERROR|WARN|FATAL)};
( my $time ) = (m{^\d{4}.{6}T(\d\d)});
print if ( $time <= 18 && $time >= 6 );
}
1;

...run as:

# ./filter logfilename > results

I presume that your log is a daily one, recreated every day. In that case, simply 'cron' this script to run sometime after 1800 hours.

Regards!

Hi, Thanks for response.

Below is the error I found with script. Please help in trouble shoot.

$ ./filter.sh ObjectSpawner.log > results.log
./filter.sh[5]: use: not found.
./filter.sh[6]: use: not found.
./filter.sh[7]: Syntax error at line 7 : `)' is not expected.

Apparently, your "filter.sh" script differs
from the suggested "filter" script, but, with
my weak psychic powers, I can see only one of
the two, and it's not yours.

cat filter.sh

Hi (again):

> Below is the error I found with script.

You changed the interpreter (she-bang) or dropped it entirely. The script's first line should read something like:

#!/usr/bin/perl

...or whatever is the absolute path to your perl executable.

You could also dynamically find perl in your PATH by using:

#!/usr/bin/env perl

Note the whitespace before the word 'perl'.
