Operating System Version Information

[Alice Daniel]

What is the command for getting the current operating system information?

[Greg Yates]

Use "sizer -v" as root. You may (probably) also need to check your patch level. For that, use a command like "dupatch -track -type patch_level". That last command gives you both the OS version and patch level.

Is there a sizer function that I can call from a program? I have a function that needs to know the OS Version in order to do some specific asynchronous calls. I have several productions systems, most have os version 4.0f but some will have os version 5.1b.

Alice,

See 'man getsysinfo', in particular the section with GSI_VERSIONSTRING.

Thanks,
Greg

You can use getsysinfo.

Or, you can use uname to get it:

[code]
# uname -a
[/code]

[Alice Daniel]

Thanks, the uname -r cmd did the trick.

[Greg Yates]

Be careful, uname doesn't return everything (in this case, 'B'). For example:

# sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Fri Sep 15 14:33:51 EDT 2006
# uname -a
OSF1 V5.1 2650 alpha
# sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Fri Sep 15 14:33:51 EDT 2006
# uname -r
V5.1
# uname -a
OSF1 V5.1 2650 alpha

All of these are the same system.
