uname

Overview ¶

Package uname implements the uname builtin command.

uname — print system information

Usage: uname [-asnrvm] [--help]

Print certain system information. With no flags, same as -s.

Reads system information from /proc/sys/kernel/ pseudo-files via the ProcProvider. The proc path is configurable via the --proc-path CLI flag or interp.ProcPath() API option (e.g., /host/proc for containers).

Flags:

-s  Print the kernel name (default when no flags given)
-n  Print the network node hostname
-r  Print the kernel release
-v  Print the kernel version
-m  Print the machine hardware name
-a  Print all of the above, in the order shown
-h, --help  Display help and exit

Data sources (relative to proc path):

-s  sys/kernel/ostype
-n  sys/kernel/hostname
-r  sys/kernel/osrelease
-v  sys/kernel/version
-m  sys/kernel/arch

Exit codes:

0  Success — requested information was written.
1  Error — unsupported platform, missing proc file, or invalid flag.
