Conclusion In this article we discussed the tail command in Linux serves as a complementary tool to the head command, specializing in displaying the last N lines of a given input.

It's going to be much faster, because when the input is not seekable, what tail needs to do is read all the standard input, line by line, keep the last 10 lines around in a buffer (in case they should be the last 10 lines); and having the input come from a pipe through your cat mechanism makes sure it's not seekable. Tail is a command which prints the last few number of lines (10 lines by default) of a certain file, then terminates. Example 1: By default "tail" prints the last 10 lines of a file, then exits.
Examples head --lines=100 print the first 100 lines head --lines=-100 print all but the last 100 lines tail --lines=100 print the last 100 lines tail --lines=-100 print all but the first 100 lines Note You may also have a look at tac. The result is clear, if you compare the word tac with cat. tac prints out all lines in reverse ordering.
