tail command
The tail command is used to output last lines of a file.
Syntax: tail [options] file
Example:

Prints last n lines of a file.
Example:

Example: Printing line from X to Y using head and tail command.
Suppose we have to print from line 5 to line 7, Here, X is 5 and Y is 7. We can use following command to print it-
# Here, X and Y are starting line number and ending line number respectively.
head -n Y main.js | tail -n Y-X+1
So, for outputing line 5 to 7, command would be:
head -n 7 main.js | tail -n 3
