=============================
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.
