tail(1)
NAME
tail − print lines from file
SYNTAX
tail [ ±[number][lbc][fr] ] [ file ]
DESCRIPTION
The tail command copies the named file to the standard output beginning at a designated place. If no file is named, the standard input is used.
Copying begins at distance +number from the beginning, or −number from the end of the input. The number is counted in units of lines, blocks or characters, according to the appended option l, b or c. When no units are specified, counting is by lines.
Specifying r causes tail to print lines from the end of the file in reverse order. The default for r is to print the entire file this way. Specifying f causes tail not to quit at end of file , but rather to reread the file repeatedly.
RESTRICTIONS
The results of the tail command are unpredictable with character special files.
