To display the last lines of a file in Linux, you can use the tail command. By default, tail shows the last 10 lines of a file. Here’s how to use it:
Basic Usage
To display the last 10 lines of a file, use:
tail filename.txt
Customizing the Number of Lines
If you want to display a specific number of lines from the end of the file, you can use the -n option followed by the number of lines you want to see. For example, to display the last 5 lines:
tail -n 5 filename.txt
Example
Assuming you have a file named example.txt, you can run:
tail example.txt
This will show the last 10 lines. If you want to see the last 3 lines, you would run:
tail -n 3 example.txt
Continuous Monitoring
Additionally, if you want to continuously monitor a file for new lines being added (like 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.
