NAME
tee - duplicate standard input
SYNOPSIS
tee [-ai] [file ...]
DESCRIPTION
The tee utility copies standard input to standard output, making a copy
in zero or more files. The output is unbuffered.
The following options are available:
-a Append the output to the files rather than overwriting them.
-i Ignore the SIGINT signal.
The following operands are available:
file A pathname of an output file.
The tee utility takes the default action for all signals, except in the
event of the -i option.
EXIT STATUS
The tee utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
Send the echoed message both to stdout and to the greetings.txt file:
$ echo "Hello" | tee greetings.txt
Hello
STANDARDS
The tee utility is expected to be IEEE Std 1003.2 ("POSIX.2") compatible.
HISTORY
The tee command first appeared in Version 7 AT&T UNIX.
