Or

    echo $NUM_PAGES | sudo tee /proc/sys/vm/nr_hugepages 

I've always found it odd that there isn't a standard command to write stdin to a file that doesn't also write it to stdout. Or that tee doesn't have an option to supress writing to stdout.

You forgot the "sudo" before "tee"

> write stdin to a file that doesn't also write it to stdout

You mean like "dd of=/path/file" ?

If you happen to have moreutils installed, you can do that with pee

    echo $NUM_PAGES | sudo pee 'cat > /proc/sys/vm/nr_hugepages'

>>TheDon+tr
why not write sh -c then?

>>direwo+bD
Because 'sh' isn't in moreutils and is harder to remember, next question.

Why use something portable when you can use cat pee?

>>thayne+(OP)
I've always thought that there should be `cat -o output-file` flag for that. GNU coreutils have miriads of useless flags and missing one actually useful flag LoL.

And probably `echo -o output-file` as well.

I physically/literally squinted when I saw disk destroyer.

I know it's useful for other things, but it has become a fearful instinct at this point.

>>TheDon+gJ
Personally? Because I hate the smell.

>>thayne+(OP)
It’s not an option or feature because it’s built into the shell. Just slap a > /dev/null on the end.

That works, but it feels wasteful to needlessly copy it, and it is verbose.
