Portable Unix shell command tee
, with some extras - read from standard input and write to standard output and files.
gulp.dest()
in middle of a pipe? NPM scripts can do as well:
{
"scripts": {
"less": "lessc main.less | postcss --use autoprefixer | ntee main.css | cleancss > main.min.css"
}
}
$ [sudo] npm install -g ntee
$ ntee --help
ntee [OPTIONS] [FILE]
Options:
-a, --append append to the given FILEs, do not overwrite
-i, --ignore-interrupts ignore interrupt signals
-s, --suppress do NOT output to stdout
-v, --version Display the current version
-h, --help Display help and usage details
$ whoami | ntee file1.txt file2.txt
Will print current user to stdout and also to file1.txt
and file2.txt
. Note that if these files already existed, they will be overwritten. Use -a
/--append
to avoid it, just like you would do with Richard Stallman's tee
:
$ whoami | ntee -a i-wont-be-overwritten.txt
-i
/--ignore-interrupts
will prevent CTRL+C from killing ntee
. Won't work on windows.
I also added an -s
/--suppress
option to suppress output to stdout. This meant to be used on npm scripts:
$ echo "Nothing will be shown in screen" | ntee -s but-it-will-be-saved-here.txt
You can always pipe:
cat long.log | sort | ntee sorted.log | head
