Linux/Unix - Print The Last 10 Lines of Each File

In Linux/Unix/GNU based system, "tail <file-name>" command will print the last 10 lines of each file.

Syntax:

tail <file-name>

Usage:

tail [OPTION]... [FILE]...

With more than one FILE, precede each with a header giving the file name.
With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
      --retry              keep trying to open a file even if it is
                           inaccessible when tail starts or if it becomes
                           inaccessible later; useful when following by name,
                           i.e., with --follow=name
  -c, --bytes=N            output the last N bytes
  -f, --follow[={name|descriptor}]
                           output appended data as the file grows;
                           -f, --follow, and --follow=descriptor are
                           equivalent
  -F                       same as --follow=name --retry
  -n, --lines=N            output the last N lines, instead of the last 10
      --max-unchanged-stats=N
                           with --follow=name, reopen a FILE which has not
                           changed size after N (default 5) iterations
                           to see if it has been unlinked or renamed
                           (this is the usual case of rotated log files)
      --pid=PID            with -f, terminate after process ID, PID dies
  -q, --quiet, --silent    never output headers giving file names
  -s, --sleep-interval=S   with -f, sleep for approximately S seconds
                           (default 1.0) between iterations.
  -v, --verbose            always output headers giving file names
      --help     display this help and exit
      --version  output version information and exit

If the first character of N (the number of bytes or lines) is a `+',
print beginning with the Nth item from the start of each file, otherwise,
print the last N items in the file.  N may have a multiplier suffix:
b 512, k 1024, m 1024*1024.

With --follow (-f), tail defaults to following the file descriptor, which
means that even if a tail'ed file is renamed, tail will continue to track
its end.  This default behavior is not desirable when you really want to
track the actual name of the file, not the file descriptor (e.g., log
rotation).  Use --follow=name in that case.  That causes tail to track the
named file by reopening it periodically to see if it has been removed and
recreated by some other program.

Example:

!! One file example !!

Linux# tail myfile1

myfile1-example-line92
myfile1-example-line93
myfile1-example-line94
myfile1-example-line95
myfile1-example-line96
myfile1-example-line97
myfile1-example-line98
myfile1-example-line99
myfile1-example-line100

!! Multiple files example !!

Linux# tail myfile1 myfile2
==> myfile1 <==
