tail - print the last few lines of a file
tail [-c n] [-f] [-n n] [file] ...
-c The count refers to characters
-f On FIFO or special file, keep reading after EOF
-n The count refers to lines
tail -n 6 # Print last 6 lines of stdin
tail -c 20 file # Print the last 20 characters of file
tail -n 1 file1 file2
# Print last line of two files
tail -n +8 file # Print the tail starting with line 8
The last few lines of one or more files are printed. The default count
is 10 lines. The default file is stdin. If the value of n for the -c or
-n flags starts with a + sign, counting starts at the beginning, rather
than the end of the file.
