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.  Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

       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.
