Name
tee — stdin stdout - file -- opt --help --version
Synopsis
tee [options
]files
Like the cat
command, the
tee
command copies standard input
to standard output unaltered. Simultaneously, however, it also
copies that same standard input to one or more files. tee
is most often found in the middle of
pipelines, writing some intermediate data to a file while also
passing it to the next command in the pipeline:
$ who | tee original_who | sort
In this command line, tee
writes the output of who
to the
file original_who
, and then passes
along that same output to the rest of the pipeline (sort
), producing sorted output on
screen.
Useful options
|
Append instead of overwriting files. |
