在Perforce中，切换客户端用户时连接到不同端口的命令是什么？

Question

在p4win gui客户端中，什么命令行相当于"Switch Port client User“？

我已经在一个端口下登录，但现在我正在尝试连接到同一服务器上的另一个端口，以便访问单独的源代码控制文件库。我假设它会涉及到使用：

p4 login

但是，读取“login”的“help”不会显示指定端口号的选项。用户名和客户端名称将保持不变，但只需更改端口号即可。

Answer 1

P4PORT配置变量存储要连接的Perforce服务器名称和端口号。您可以将此值设置为环境变量，或者，如果您使用的是Windows，则可以使用'p4 set‘在注册表中设置此值：

p4 set P4PORT=perforce:1669

要查看P4PORT的当前值，请执行以下操作：

> p4 set P4PORT
P4PORT=perforce:1669

Answer 2

如果你想对任何P4命令通用地这样做，那么可以通过"p4帮助用法“找到一般形式。

简而言之，

p4 -p <your port> login 

会按你的要求去做。请注意，在用法帮助中，您可以从命令行指定大多数内容，例如客户端规范、用户名、密码等。

Answer 3

例如：

p4 set P4PORT=1666

从帮助中：

C:\> p4 help environment

See 'p4 help set' for details specific to Windows.  The syntax for
setting an environment variable depends on the OS/shell.  Note that many
shells allow the setting of shell variables separate from environment
variables - Perforce cannot see the shell variable, only the environment
variable.

If you are a typical user then the only variables of interest are
$P4CLIENT, $P4PORT and $P4PASSWD.


C:\> p4 help set

set -- Set variables in the registry (Windows only)

p4 set [ -s -S service ] [ var=[value] ]

    'p4 set' sets the registry variables used by Perforce on Windows
    platforms.  Normally, the variable 'var' is set to 'value'.
    If 'value' is missing, the variable 'var' is unset.  Without
    any arguments at all, 'p4 set' list variable settings.

    The -s flag causes 'p4 set' to set variables for the whole system
    rather than for the user.  You must have NT administrator powers
    to use this.

    The -S service flag causes 'p4 set' to set variables for the named
    service.  You must have NT administrator powers to use this.

    Currently, registry variable entries may be overridden by environment
    variables and (in some cases) flags on the command line.
    See 'p4 help environment' for a list of environment/registry variables.
