June 6, 1993 TEE 1

### NAME

tee - pipe fitting

### 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.

The tee utility exits 0 on success, and >0 if an error occurs.

### STANDARDS

The tee function is expected to be POSIX IEEE Std 1003.2 (``POSIX.2'') compatible.
