DMESG Analyzer
Implement a system log analyzer and classifier for GNU/Linux. In this particular case, a sample log output file is provided. It's highly recommended to implement in a Linux-based
Requirements
The program must be implemented in the C programming language.
You program will classify log entries by the <log_type>: prefix
Those log entries that don't follow the <log_type>: convention will go to the General classification.
Repeated log classes are not allowed.
Use the dmesg-analyzer.c template
The solution must use at least 3 of the following system calls:
open()
read()
write()
lseek()
close()
Don't forget to handle errors properly
Sample Execution
./dmesg-analizer -input dmesg.txt -output dmesg_report.txt
Sample Expected output file dmesg_report.txt
