What command checks the log file?

To check the contents of a log file, you can use the cat command. For example, if your log file is named combined_output.log, you would use:

cat combined_output.log

This command will display the contents of the log file in the terminal. If you want to view the last few lines of the log file, you can use the tail command:

tail combined_output.log

And if you want to view the first few lines, you can use the head command:

head combined_output.log
