    Returns the home directory of the current user.

    Example:

    1. os.homedir()

22. def loadavg(): Array[Int]

    

    Returns an array containing the 1, 5, and 15 minute load averages.

    Returns an array containing the 1, 5, and 15 minute load averages.

    The load average is a measure of system activity, calculated by the operating system and expressed as a fractional number. As a rule of thumb, the load average should ideally be less than the number of logical CPUs in the system.

    The load average is a very UNIX-y concept; there is no real equivalent on Windows platforms. That is why this function always returns [0, 0, 0] on Windows.

    Example:

    1. os.loadavg()

27. def platform(): String

    

    Returns the operating system platform.

34. def totalmem(): Double

    

    Returns the total amount of system memory in bytes.

    Returns the total amount of system memory in bytes.

    Example:

    1. os.totalmem()

35. def type(): String

    

    Returns the operating system name.

    Returns the operating system name. For example 'Linux' on Linux, 'Darwin' on OS X and 'Windows_NT' on Windows.

    Example:

    1. os.type()

36. def uptime(): Double

    

    Returns the system uptime in seconds.

    Returns the system uptime in seconds.

    Example:

    1. os.uptime()

37. def userInfo(options: UserInfoOptions = js.native): UserInfoObject

    

    The os.userInfo() method returns information about the currently effective user -- on POSIX platforms, this is typically a subset of the password file.

    The os.userInfo() method returns information about the currently effective user -- on POSIX platforms, this is typically a subset of the password file. The returned object includes the username, uid, gid, shell, and homedir. On Windows, the uid and gid fields are -1, and shell is null.

    The value of homedir returned by os.userInfo() is provided by the operating system. This differs from the result of os.homedir(), which queries several environment variables for the home directory before falling back to the operating system response.

    returns

    a user information object
