Dear coreutils developers,
I have read many tutorials, where a secret is written to a file, which
is protected afterwards, like this:
```
generate_secret > keyfile
chmod 0600 keyfile
```
I hope that the following approach would have been intuitive and more
secure, as the keyfile was never readable:
```
generate_secret | install -x -m 0600 keyfile
```
where "-x" would indicate, that stdin shall be used as source. Please
take "x" as a placeholder; any letter works for me.
Do you like the idea to support stdin?
Best regards,
Lars
Well /dev/stdin works for this. I.e. this works:
echo secret | install -m 0600 /dev/stdin keyfile
cheers,
