Como faço isso sem o PATH do sistema sendo duplicado no usuário PATH?
Use a opção /m .
setx /m PATH "%PATH%;%~dp0"
Notas:
-
/m- Defina a variável no ambiente do sistema HKLM. (O padrão é o ambiente local HKCU)
setx usage
F:\test>setx /?
SetX has three ways of working:
Syntax 1:
SETX [/S system [/U [domain\]user [/P [password]]]] var value [/M]
Syntax 2:
SETX [/S system [/U [domain\]user [/P [password]]]] var /K regpath [/M]
Syntax 3:
SETX [/S system [/U [domain\]user [/P [password]]]]
/F file {var {/A x,y | /R x,y string}[/M] | /X} [/D delimiters]
Description:
Creates or modifies environment variables in the user or system
environment. Can set variables based on arguments, regkeys or
file input.
Parameter List:
/S system Specifies the remote system to connect to.
/U [domain\]user Specifies the user context under which
the command should execute.
/P [password] Specifies the password for the given
user context. Prompts for input if omitted.
var Specifies the environment variable to set.
value Specifies a value to be assigned to the
environment variable.
/K regpath Specifies that the variable is set based
on information from a registry key.
Path should be specified in the format of
hive\key\...\value. For example,
HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Control\TimeZoneInformation\StandardName.
/F file Specifies the filename of the text file
to use.
/A x,y Specifies absolute file coordinates
(line X, item Y) as parameters to search
within the file.
/R x,y string Specifies relative file coordinates with
respect to "string" as the search parameters.
/M Specifies that the variable should be set in
the system wide (HKEY_LOCAL_MACHINE)
environment. The default is to set the
variable under the HKEY_CURRENT_USER
environment.
/X Displays file contents with x,y coordinates.
/D delimiters Specifies additional delimiters such as ","
or "\". The built-in delimiters are space,
tab, carriage return, and linefeed. Any
ASCII character can be used as an additional
delimiter. The maximum number of delimiters,
including the built-in delimiters, is 15.
/? Displays this help message.
NOTE: 1) SETX writes variables to the master environment in the registry.
2) On a local system, variables created or modified by this tool
will be available in future command windows but not in the
current CMD.exe command window.
3) On a remote system, variables created or modified by this tool
will be available at the next logon session.
4) The valid Registry Key data types are REG_DWORD, REG_EXPAND_SZ,
REG_SZ, REG_MULTI_SZ.
5) Supported hives: HKEY_LOCAL_MACHINE (HKLM),
HKEY_CURRENT_USER (HKCU).
6) Delimiters are case sensitive.
7) REG_DWORD values are extracted from the registry in decimal
format.
