tail: Print the last lines of a given file and keep reading file until `Ctrl + C`.
$ tail -f ${filename}
try on your machine
The command "tail -f ${filename}" is used to continuously monitor a file for any new changes or updates appended to it. The term "tail" refers to the tail end of a file, while the "-f" option stands for "follow", indicating that the command should keep watching the file.
When executed, the command will display the last few lines of the specified ${filename} file and continue to show any new lines appended to it in real-time. This is particularly useful when monitoring log files or any other constantly updated files, allowing you to keep track of the latest changes without needing to manually refresh or reopen the file.
