p4 set

Synopsis

Syntax

Description

On Windows, you can set the values of these variables in the registry with p4 set; on other operating systems, Perforce uses environment variables for the same purpose.

To set the value of a registry variable for the current user, use p4 set var=value. Windows administrators can use p4 set -s var=value to set the registry variable's default values for all users on the local machine.

Windows administrators running the Perforce server as a service can set variables used by the service (for instance, P4JOURNAL and others) with p4 set -S svcname var=value.

To unset the value for a particular variable, leave value empty.

To view a list of the values of all Perforce variables, use p4 set without any arguments. On UNIX, this displays the values of the associated environment variables. On Windows, this displays either the MS-DOS environment variable (if set), or the value in the registry and whether it was defined with p4 set (for the current user) or p4 set -s (for the local machine).

p4 set can be used on non-Windows operating systems to view the values of variables, but if you try to use p4 set to set variables on non-Windows operating systems, Perforce will display an error message.

Options

-s	Set the value of the registry variables for the local machine. Without this flag, p4 set sets the variables in the HKEY_CURRENT_USER hive; when you use the -s flag, the variables are set in the HKEY_LOCAL_MACHINE hive. These locations are reflected in the output of p4 set on Windows.
-S svcname	Set the value of the registry variables as used by service svcname. You must have administrator privileges to do this.
g-opts	See the Global Options section.

• You'll find a listing and discussion of the Perforce variables in the Environment Variables section of this manual.

• Changes to registry values under Windows affect the local machine only; an administrator setting P4JOURNAL for a Perforce NT service must be present at the machine running the service.

• On Windows, you can override the values of the registry keys in any of three ways:
  • Environment variables with the same names have precedence;

  • Values within P4CONFIG files have precedence over both of these;

  • The global option flags have the highest precedence.

• If you're working in a UNIX-like environment on a Windows machine (e.g. Cygwin), use environment variables instead of p4 set. (In such cases, the Perforce Comnand-Line Client behaves just as though it were in a UNIX environment.)

Examples

p4 set	On all platforms, display a list of Perforce variables without changing their values.
p4 set P4MERGE=	On Windows, unset the value of P4MERGE.
p4 set P4PORT=tea:1666	On Windows, set a registry variable telling Perforce client programs to connect to a Perforce server at host tea, port 1666. The variable would be set only for the current local user. .
p4 set -s P4PORT=tea:1666	Set P4PORT as above, but for all users on the system. You must have administrative privileges to do this.
p4 set -S p4svc P4PORT=1666	For the NT service p4svc, instruct p4s.exe to listen on port 1666 for incoming connections from Perforce client programs. You must have administrative privileges to do this.
p4 set P4EDITOR="C:\File Editor\editor.exe"	On Windows, for the current local user, set the path for the default text editor. The presence of spaces in the path to the editor's executable requires that the path be enclosed in quotation marks.
