tee

clone output stream 

Command


SYNOPSIS

tee [-ai] [file ...]


DESCRIPTION

The tee command clones an output stream. It copies the standard input to each output file as well as to the standard output.

Options

-a 

appends to (rather than overwrites) each output file.

-i 

ignores interrupt signals, making it suitable for use as a background process. Since Windows systems do not support signals, this option does nothing on those systems.


EXAMPLES

prog | tee file

This runs the program prog and pipes the program's standard output into tee. As a result, tee writes the output to both the standard output and the specified file.


DIAGNOSTICS

Possible exit status values are:

0 

Successful completion.

1 

Failure due to any of the following:

— out of memory
— I/O error reading or writing to a file
— error creating an output file
— error opening an output file for append
2 

Failure due to invalid command line option.
