NAME
       tee - read from standard input and write to standard output and files

SYNOPSIS
       tee [OPTION]... [FILE]...

DESCRIPTION
       Copy standard input to each FILE, and also to standard output.

       -a, --append
              append to the given FILEs, do not overwrite

       -i, --ignore-interrupts
              ignore interrupt signals

       -p     diagnose errors writing to non pipes

       --output-error[=MODE]
              set behavior on write error.  See MODE below

       --help display this help and exit

       --version
              output version information and exit

   MODE determines behavior with write errors on the outputs:
       warn   diagnose errors writing to any output

       warn-nopipe
              diagnose errors writing to any output not a pipe

       exit   exit on error writing to any output

       exit-nopipe
              exit on error writing to any output not a pipe

       The default MODE for the -p option is ’warn-nopipe’.  The default opera‐
       tion when --output-error is not specified, is to exit immediately on er‐
       ror writing to a pipe, and diagnose errors writing to non pipe outputs.

Title: tee - Read from standard input and write to standard output and files

Summary

The `tee` command reads from standard input and writes to both standard output and specified files. It includes options for appending to files, ignoring interrupts, diagnosing write errors, and controlling behavior on write errors to pipes and non-pipes. The document provides information on how to use the command, report bugs, and access full documentation.
