How to view file's end?

To view the end of a file in Linux, you can use the tail command. By default, tail displays the last 10 lines of a file. Here’s how to use it:

tail filename.txt

If you want to view a specific number of lines from the end, you can use the -n option. For example, to view the last 20 lines:

tail -n 20 filename.txt

If you want to continuously monitor the end of a file (for example, a log file), you can use the -f option:

tail -f filename.txt

This will keep the terminal open and display new lines as they are added to the file.
