   3 NAME
   4      tee - replicate the standard output
   5 
   6 SYNOPSIS
   7      tee [-ail] [file]...
   8 
   9 DESCRIPTION
  10      tee copies standard input to standard output, making a copy in zero or
  11      more files.  tee does not buffer its output by default (but see the -l
  12      option).  The options determine if the specified files are overwritten or
  13      appended to.  If a write to a file fails, tee continues to write to other
  14      files although it exits with a non-zero exit status.
  15 
  16    ksh93
  17      The tee built-in in ksh93(1) is associated with the /bin and /usr/bin
  18      paths.  It is invoked when tee is executed without a pathname prefix and
  19      the pathname search finds a /bin/tee or /usr/bin/tee executable.
  20 
  21 OPTIONS
  22      The following options are supported:
  23 
  24      -a, --append  Appends the output to the files rather than overwriting
  25                    them.
  26 
  27      -i, --ignore-interrupts
  28                    Ignores SIGINT signal.
  29 
  30      -l, --linebuffer
  31                    Sets the standard output to be line buffered.
  32 
  33 OPERANDS
  34      The following operands are supported:
  35 
  36      file          A path name of an output file.  Processing of at least 13
  37                    file operands is supported.
