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 start-
              ing 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  re-
              named  (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.
