NAME

       tail - output the last part of files

SYNOPSIS

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

DESCRIPTION

       Print  the  last  10  lines of each FILE to standard output.  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.

       -c, --bytes=K
              output the last K bytes; alternatively,  use  -c  +K  to  output
              bytes starting with the Kth of each file

       -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=K
              output the last K lines, instead of the last 10; or use -n +K to
              output lines starting with the Kth

       --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).  With
              inotify, this option is rarely useful.

       --pid=PID
              with -f, terminate after process ID, PID dies

       -q, --quiet, --silent
              never output headers giving file names

       --retry
              keep  trying  to  open  a  file  even  when  it  is  or  becomes
              inaccessible;   useful   when  following  by  name,  i.e.,  with
              --follow=name

       -s, --sleep-interval=N
              with -f, sleep for approximately N seconds (default 1.0) between
              iterations.   With inotify and --pid=P, check process P at least
              once every N seconds.

       -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 K (the number of bytes or lines)  is  a  `+',
       print  beginning  with  the  Kth  item  from  the  start  of each file,
       otherwise, print the last K items in the file.  K may have a multiplier
       suffix:  b  512,  kB  1000,  K  1024,  MB  1000*1000,  M  1024*1024, GB
       1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.

       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  in  a  way that accommodates
       renaming, removal and creation.
