Simpletail must support at least the following functions: - show last n lines of a file - optional number of lines option - help message - error reporting in case of invalid parameter or file Please note that live watch function (as in tail -f option) is not required. For example: >java -jar [login to view URL] -n 3 [login to view URL] > return result; > } >} >java -jar [login to view URL] –help >usage: simpletail [-n lines] file >java -jar [login to view URL] -n -1 [login to view URL] >ERROR: invalid number of lines -n 3.
