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
       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.
