[9front] Equivalent of Unix uname

[9front] Equivalent of Unix uname

[rockyhotas]

Hello!
I'm trying to move the first steps into Plan9.
It is not Unix, the user is often warned about this. However, some tools
are available in both systems with almost the same usage, like uptime(1)
for example. Is there anything equivalent to `uname'? I couldn't find
such a tool nor in

  <https://fqa.9front.org/fqa8.html>

neither in

  <https://wiki.9front.org/unix2plan9>

If there is not a perfect equivalent tool, is it anyway possible to list
some basic information about the current system? For example the OS 
name,
the kernel version, the architecture, the hostname.

Bye!

Rocky

kernels aren't versioned. the os name isn't reported; you're expected to 
know you're on a plan 9 system. `echo $sysname' will tell you the system 
name. `echo $cputype' will tell you the arch.

9 doesn't need a uname command. $sysname matters depending on context, 
but $cputype really doesn't; the 9 compilers are natively cross-arch.

There is /dev/osversion but its not really particularly insightful.
Uname is generally used to differentiate different Unixen from
each other, so I don't see why it would be particularly useful
on Plan 9.

We also do not generally have version of the kernel per se,
at least not in the same way something like Linux does.
For architecture there is $cputype and for host name there
is $sysname.


Hope that helps,
moody

plan9 is distributed with binaries, but installations are kept
up-to-date via source updates from git, so in practice, before you run
sysupdate and mk install yourself you may check the current git
revision.

also keep in mind that in the canonical deployments you will have only
one central fileserver for all your cpu servers and terminals, so if
you know the version of one of your computers you should automatically
be able to imply the version of all other computers.

fwiw if you do need for sh shell scripts, ape/psh does mount an `uname
` command into your PATH, AFAIK there's no need for a uname command
elsewhere since we dont have a (updated) ssh server for you to connect
remotely and maybe get confused on where are you running things, and
even if we had, you can notice it due to lacking tty
emulation/interaction

/rc/bin/sysinfo is also handy.

Peace,

Yes, in fact I thought kernel versions and OS type were handled
similarly to Linux or other Unix-like system, but that's not the case
for Plan9.

Thanks to you and to all those who added their suggestions.
You have been very helpful!

ape/uname is pretty useless for the purpose
of what they were asking for. It just reads out
the various environment variables that were already
discussed.
