# 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.

# EXIT STATUS

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.
