TEE(1) BSD Reference Manual TEE(1)
tee - pipe fitting
tee [-ai] [file ...]
The tee utility copies standard input to standard output, making a copy
in zero or more files. The output is unbuffered.
The options are as follows:
-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.
The tee utility exits 0 on success or >0 if an error occurred.
The tee function is expected to be POSIX IEEE Std 1003.2 ("POSIX.2") com-
patible.
