TAIL(1)                          User Commands                         TAIL(1)
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=[+]NUM
              output  the  last  NUM  bytes; or use -c +NUM to output starting
              with byte NUM of each file
       -f, --follow[={name|descriptor}]
              output appended data as the file grows;
              an absent option argument means 'descriptor'
       -F     same as --follow=name --retry
       -n, --lines=[+]NUM
              output the last NUM lines, instead of the last  10;  or  use  -n
              +NUM to output starting with line NUM
       --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 if it is inaccessible
       -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
       -z, --zero-terminated
              line delimiter is NUL, not newline
       --help display this help and exit
       --version
              output version information and exit
       NUM 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 descrip-
       tor (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.
