Displays the output of a program and copies it into a file.
tee [ -a ] [ -i ] [ File ... ]
The tee command reads standard input, then writes the output of a program to standard output and simultaneously copies it into the specified file or files.
|-a||Adds the output to the end of File instead of writing over it.|
This command returns the following exit values:
|0||The standard input was successfully copied to all output files.|
|>0||An error occurred.|
Note: If a write to any successfully opened File operand is not successful, writes to other successfully opened File operands and standard output will continue, but the exit value will be >0.
