New toy: reboot/halt/poweroff
Minor cleanup of reboot
Don't use $CC without $CROSS_COMPILE because $HOSTCC could be something else entirely.
I noticed the user count was missing and added this, borrowing a bit of code from toys/posix/who.c.
watch: Add support for -e option, remove memory leak and deal with not-wide terminals
Refactor terminal querying.
Here's a revised cpio.
I've reduced the use of malloc(), dropped an extra function call, and
-at least in theory- allowed proper handling of non-regular files.
(If we have a file we can't read, we still should record it when it's
of a type where file content is ignored).
Cleanup nl, add support for more bits of posix.
Promote nl from pending to posix, and add tests.
