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.
