Uname

The uname command prints system information, like the kernel name or machine architecture.

Availability

On nearly every Unix-like system, the uname program is available. This includes all desktop-oriented GNU/Linux distributions, OpenBSD, FreeBSD, and more.

Usage

uname has many flags, including -a, which will make the program act as if all of the below flags were given.

• -s Prints the kernel name.
• -r Prints the kernel release.
• -v Prints information about how and when the kernel was compiled.
• -m Prints your machine's architecture.
• -o Prints operating system name, often "GNU/Linux".
• -n Prints your system's hostname.
• -p Prints your processor architecture, sometimes will report "unknown".
• -i Prints your hardware platform, sometimes will report "unknown".
