Standard syntax: tail [-f] [-c Number |-n Number |-m Number |-B Number |-k Number] [File] Description: The tail command starts the file specified by the parameter is written to the standard output. If no file is specified, standard input is used. The Number variable specifies the Number of units to be written to the standard output. The value of the Number variable can be a positive or negative integer. If the value is preceded by a plus sign, the file is written to the standard output starting with the number of units specified at the beginning of the file. If there is a minus sign before the value, the file is written to the standard output starting from the number of units specified at the end of the file. If no + (plus sign) or-(minus sign) exists before the value, read the file starting from the specified unit number at the end of the file. The Number variable determines the unit type of the start point of the count by The-B,-c,-k,-m, and-n flags. If no flag is specified, the tail command reads the last 10 lines of the specified file and writes it to the standard output. This is the same as entering-n10 in the command line.
