tail command help


       tail - output the last part of files
 

SYNOPSIS

       ../src/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.
 
       --retry
              keep trying to open a file even if it is inaccessi­
              ble  when tail starts or if it becomes inaccessible
              later -- useful only with -f
 
       -c, --bytes=N
              output the last N bytes
 
       -f, --follow[={name|descriptor}] output appended data as
       the file grows;
              -f, --follow, and --follow=descriptor  are  equiva­
              lent
 
       -n, --lines=N
              output the last N lines, instead of the last 10
 
       --max-unchanged-stats=N see the texinfo documentation
              (the default is 5)
 
       --max-consecutive-size-changes=N see the texinfo documen­
       tation
              (the default is 200)
 
       --pid=PID
              with -f, terminate after process ID, PID dies
 
       -q, --quiet, --silent
              never output headers giving file names
 
       -s, --sleep-interval=S
              with -f, sleep S seconds between iterations
 
       -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 N (the number of bytes or lines)
       file.   N  may  have a multiplier suffix: b for 512, k for
       1024, m for 1048576 (1 Meg).  A first OPTION of -VALUE  or
       +VALUE  is treated like -n VALUE or -n +VALUE unless VALUE
       has one of the [bkm] suffix multipliers, in which case  it
       is treated like -c VALUE or -c +VALUE.
 
       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 by reopening it
       periodically to see if it has been removed  and  recreated
       by some other program.
