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
tee accepts the following options:
–a appends to (rather than overwrites) each output file.
–i ignores interrupt signals, making it suitable for use as a background process.

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.
