How to search for log files by keyword in Linux?

In a Linux system, you can utilize the grep command to search for keywords in log files.

For example, if you want to search for lines containing the keyword “error” in a log file named logfile.txt, you can use the following command:

grep "error" logfile.txt

This will display all lines in the logfile.txt that contain the keyword ‘error’.

You can also combine grep with other commands to perform more complex searches in log files, such as using grep -i to ignore case sensitivity, or using grep -r to recursively search all log files in a directory.

I hope this can help you search for log files by keyword! If you have any other questions, please feel free to let me know.
