ExpandFromEnvironment expands a string containing variables with values from the environment.

ExpandParameter expands a variable expressed in a string `s` with its value returned by the mapping function.

ExpandUnixParameter expands a ${param} or $param in `s` based on the mapping function See https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html os.Expand is used under the bonnet and so, only basic parameter substitution is performed.

ExpandWindowsParameter expands a %param% in `s` based on the mapping function See https://learn.microsoft.com/en-us/previous-versions/troubleshoot/winautomation/product-documentation/best-practices/variables/percentage-character-usage-in-notations https://devblogs.microsoft.com/oldnewthing/20060823-00/?p=29993 https://github.com/golang/go/issues/24848 WARNING: currently the function only works with one parameter substitution in `s`.

GetCurrentUser returns information about the current platform's user and expands its home directory.

GetDefaultHomeDirectory returns the default home directory for a user based on the convention listed in https://en.wikipedia.org/wiki/Home_directory#Default_home_directory_per_operating_system.

GetHomeDirectory returns the home directory of a user.

GetUser returns information about a user and expands its home directory.

HasUser checks whether a user exists.

IsUserAdmin states whether the user is a superuser or not.

IsWindows checks whether we are running on Windows or not.

LineSeparator returns the line separator.

NodeName returns the system node name (equivalent to uname -n).

PlatformInformation returns the platform information (equivalent to uname -s).

RemoveGroup removes a group from the platform.

RemoveUser removes a user from the platform when only the username is known.

RemoveWithPrivileges removes a directory even if it is not owned by user (equivalent to sudo rm -rf).

SubstituteParameter performs parameter substitution on all platforms.

SubstituteParameterUnix performs Unix parameter substitution: See https://tldp.org/LDP/abs/html/parameter-substitution.html - the first element is the parameter to substitute - if find and replace is also wanted, pass the pattern and the replacement as following arguments in that order.

SubstituteParameterWindows performs Windows parameter substitution: See https://ss64.com/nt/syntax-replace.html - the first element is the parameter to substitute - if find and replace is also wanted, pass the pattern and the replacement as following arguments in that order.

SystemInformation returns the system information (equivalent to uname -a).

UnixLineSeparator returns the line separator on Unix platform.

UpTime returns system uptime.

WithPrivileges redefines a command so that it is run with elevated privileges.
