Help with Shell Scripting
Hi Guys,
I need some help in creating a bash script that does the following:
Currently, we have a centralized log file that grows to 50MB per day. This log file is updated regularly.
Our task is to create a script that runs every 30 minutes that will read the log file and grep for a specific pattern and dumps it to another file. The next run should read the same log file but only capture the patterns that run after previous run. Then create a new file.
At the end of the day, the script should create a maximum of 48 new files.
Hope you help me.

nnstats
NNSTATS(1m) NNSTATS(1m)
NAME
nnstats - display nnmaster collection and expire statistics
SYNOPSIS
nnstats [ -lt ] [ -d month day ] [ -m month ] [ logfile ]...
DESCRIPTION
nnstats will extract the collection (C) and expiration (X) entries from the log file and calculate total and average number of articles,
groups and elapsed time per day, per month, or for the duration of the whole log file.
Normally only a summary for the specified period is printed. If -l is specified, the statistics for each day in the period is also
printed, and if -t is specified the summary is not printed.
Normally the statistics is collected for all days in the log files (or the current log file if one is not specified).
If "-m month" is specified, the statistics for that month is calculated. The month is specified in normal date notation, i.e. a capital-
ized three letter abbreviation like Jan, Feb, ...
If "-d month day" is specified, the statistics for that date only is calculated and printed.
FILES
../Log The log file
SEE ALSO
nn(1), nnusage(1M), nnadmin(1M), nnmaster(8)
NOTES
If nnmaster is run with options -LCX, nnstats will not work, because the necessary entries are not written to the log file.
