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.
