You know, sysctl is actually a really badly specified program. Not the recent submission, I mean the original one.
If you do something like this: sysctl net.unix.max_dgram_qlen kernel.sched_domain.cpu1 It lists the keys under there. That _implies_ that sysctl with no arguments should show all keys, but instead it shows a usage message and says "-a" (or -A) shows all keys. But if you do -a and a key, you get the usage message (not even an error, just the usage message), and if you put the -a at the end it says "-a" is an unknown key. Next up, assigning keys. You can go "sudo sysctl net.ipv4.conf.lo.forwarding=1" without specifying -w, because the = tells it you're doing an assignment. The -w seems like a NOP, except: $ sysctl -w net.ipv4.conf.lo.forwarding error: "net.ipv4.conf.lo.forwarding" must be of the form name=value I.E. that option exists to cause errors. Next up, "-n". With grep the _default_ behavior is to print just the matches when searching a single file, and to print the filename when searching multiple files. Here, the default is "don't work in scripts", and then you add options to work in scripts. Sigh. Yeah, in the absence of any kind of spec we probably have to match this behavior, and the submitted version does a decent job of that. But... ow.
