p4 コマンドの引数で接続先や使用するクライアント名を指定する
p4 コマンドによる接続先のサーバは P4PORT 変数、使用するクライアントは P4CLIENT 変数で指定しておくのが一般的な使い方ですが、p4 コマンド実行時のオプションで指定することも可能です。
一時的に接続先を変えたい場合や、スクリプト内で p4 コマンドを実行したい場合などに便利です。
$ p4 -p <port> -u <user> -P <pass> <command>
$ p4 -p p4.example.com:2666 -u maku -P pass files //...
$ p4 -p 192.168.0.1:1666 print //depot/dir/filename
ちなみにこのようなパラメータ (options) として、他にどのようなものを指定できるかは、p4 help usage で確認することができます。
$ p4 help usage
Perforce client usage:
p4 [options] command [arg ...]
p4 -V
options:
-b batchsize -c client -C charset -d dir -H host -G -L language
-p port -P pass -s -Q charset -u user -x file -z tag
The -b batchsize specifies a batch size (number of arguments) to
use when processing a command from a file '-x' (default 128).
The -c flag specifies the client name, overriding the value of
$P4CLIENT in the environment and the default (the hostname).
The -C flag specifies the client's character set, overriding the
value of $P4CHARSET in the environment. See 'p4 help charset'
for more information.
The -d flag specifies the current directory, overriding the value of
$PWD in the environment and the default (the current directory).
The -G flag formats all output (and batch input for form commands
with -i) as marshalled Python dictionary objects.
The -H flag specifies the host name, overriding the value of
$P4HOST in the environment and the default (the hostname).
The -L flag specifies the language for text messages from the
server, overriding the value of $P4LANGUAGE in the environment.
Setting this option only works if the administrator has loaded
support for non-English messages into the server database.
The -p flag specifies the server's listen address, overriding the
value of $P4PORT in the environment and the default (perforce:1666).
The -P flag specifies the password, overriding the value of
$P4PASSWD in the environment.
The -Q flag specifies the client's command character set,
overriding the value of $P4COMMANDCHARSET in the environment.
See 'p4 help charset' for more information.
The -s flag causes the p4 command line client program to prefix
each line of output with a tag (error, warning, info, text, exit)
to make it easier to use for scripting.
The -u flag specifies the user name, overriding the value of
$P4USER, $USER, and $USERNAME in the environment.
The -x flag instructs p4 to read arguments, one per line, from the
specified file. If you specify '-', standard input is read.
The -V flag displays the version of the p4 client command and exits.
The -z tag option returns output of reporting commands in the
format returned by 'p4 fstat'.
