Sys.info: Extract System and User Information

Description

Reports system and user information.

Usage

Sys.info()

Arguments

Value

A character vector with fields

sysname

The operating system name.

release

The OS release.

version

The OS version.

nodename

A name by which the machine is known on the network (if any).

machine

A concise description of the hardware, often the CPU type.

login

The user's login name, or "unknown" if it cannot be ascertained.

user

The name of the real user ID, or "unknown" if it cannot be ascertained.

effective_user

The name of the effective user ID, or "unknown" if it cannot be ascertained. This may differ from the real user in ‘set-user-ID’ processes.

The first five fields come from the uname(2) system call. The login name comes from getlogin(2), and the user names from getpwuid(getuid()) and getpwuid(geteuid()) The last three fields give the same value on Windows.

Details

This uses POSIX or Windows system calls. Note that OS names might not be what you expect: for example macOS identifies itself as Darwin and Solaris as SunOS.

Sys.info() returns details of the platform R is running on, whereas R.version gives details of the platform R was built on: the release and version may well be different.

See Also

.Platform, and R.version. sessionInfo() gives a synopsis of both your system and the R session (and gives the OS version in a human-readable form).

Examples

Run this code
# NOT RUN {
Sys.info()
## An alternative (and probably better) way to get the login name on Unix
Sys.getenv("LOGNAME")
# }
