I am checking the log on a server multiple times throughout the day. Each time, I open the log in NotePad++ and search for key words such as "warn" or "error" and then review the error or warning to determine my next course of action. Instead of checking it multiple times a day, is there a way to run a script to check the log for errors or warnings?

Can you just use grep to find lines containing the warning error keywords? If you're using a more complex log format, you need to describe it. Then people can give you a sed or Python based script.

using CRON or AT you can set up a schedule to run a script or program according to any desired schedule such as at specific times repeated every day or once per week.
Look up linux CRON, and crontab -e
as well as linux AT https://linux.die.net/man/1/at
As for a script or program to be run, that would be up to you to implement. Does not need to be complex, simply do a word search within specific log file, if found then do something.
that something can be send an email saying found, or just create a text file with either "NOT FOUND" or "FOUND with detail"
you would want to learn BASH shell scripting.
first thing that comes to mind is in linux grep -l "word_pattern" filename
if the grep command does not find your word pattern within the file, then it returns nothing and that can be used within a BASH shell script as your not found condition.

Thank you. That was very helpful. I apologize as I should clarify that my attempt was to use BASH and make it as basic as possible. I was asked if I could write a bash script that would check the log for errors, and return a well-defined error message (if there were errors). Then another team could call that script using one of their other monitoring agents, and alert based on that. I don't know if that helps or makes any sense.
