Log Pars is a basic linux based log parser written in Python.
If you are looking for one specific word:
python3 logpars.py [error message you are looking for] [/var/log/TARGETLOG]
If you are looking for more than one word string, use quotation marks:
python3 logpars.py ["error message you are looking for"] [/var/log/TARGETLOG]
Whole script is written in Python 3.8, which is recommended for best functionality. Something might not work well in older versions. Python is free to download from official website for all platforms.
