<kyak> ubuntu "command-line system" installation (https://help.ubuntu.com/community/Installation/LowMemorySystems) takes up 159 Mb of RAM..
<kyak> in contrast, arch linux installation takes up 57 Mb
<kyak> which is still too much in my opinion.. i think it used to be 13 Mb before they switched to systemd
<kyak> or maybe i confuse it with nanonote :)

<larsc> the nanonote kernel alone is almost that size
<whitequark> is there a shell command (*not* a bash builtin) that implements ! ?
<whitequark> something like... not
<whitequark> not true; echo $? # 0
<larsc> well, test
<whitequark> test doesn't invoke commands though
<larsc> depends on your shell I guess
<whitequark> bash
<whitequark> oh
<whitequark> >(*not* a bash builtin)
<whitequark> exactly because of this
<whitequark> /usr/bin/[ doesn't invoke commands.
<larsc> run a subshell ;)
<whitequark> eugh
<kyak> what is that you are trying to do in the first place?
<whitequark> exactly what I described. I have a command which returns 1 on success and I need a negation of it
<larsc> but why does it have to be not a shell built-in
<whitequark> because if $x doesn't invoke shell builtins
<whitequark> I eventually caved and did sh -c "$x" instead
<kyak> can you invoke your command first, and then use "$?" in test?
<whitequark> nah
<whitequark> nevermind though, it works with subshell

<wpwrak> whitequark: eval "$x" :)
<wpwrak> (with ! and whatever builtin you fancy)
<whitequark> oh, ha, that'd actually be what I want
