[glug-t] One Day One GNU/Linux Command (TAIL)

One Day One GNU/Linux Command
=============================

tail - Output the last part of files.

Summary: 

Display the last 10 lines of each FILE to stdout. With more than one
FILE, precede each with a header giving the file name.

Examples:

$ tail midas.txt -- Show only the last 10 Lines.

$ tail f1 f2 -- Show the last 10 lines of 2 files with small header.

$ tail -vn 5 myfile -- Show only last 5 Lines with header.

$ tail -c 12 myfile -- Show only last 12 Bytes.

$ tail -q myfile -- Don't show headers.

$ tail --retry myfile -- Keep retrying to open myfile.

$ tail -f maillog -- Output appended with file data as the file grows.
                     Useful to monitor logs.

$ tail -f -s 10 maillog -- Once in every 10s update the output.

$ tail -f --pid=200 myfile -- Terminate tail after PID(200) dies.
