nisdefaults 說(shuō)明

在參閱nisdefaults實(shí)用程序輸出是通過(guò)調(diào)用NIS +本地名稱函數(shù)返回的默認(rèn)值。沒(méi)有指定任何選項(xiàng)，所有默認(rèn)設(shè)置都將以詳細(xì)格式打印。使用options時(shí)，只有該選項(xiàng)以適合shell 腳本的簡(jiǎn)潔形式顯示。請(qǐng)參見(jiàn)下面的示例。

nisdefaults 語(yǔ)法

nisdefaults [-adghprstv]

選件

-a	以簡(jiǎn)潔的格式打印所有默認(rèn)設(shè)置。
-d	打印默認(rèn)域名。
-g	打印默認(rèn)的組名。
-h	打印默認(rèn)主機(jī)名。
-p	打印默認(rèn)的主體名稱。
-r	打印將用于創(chuàng)建新對(duì)象的默認(rèn)訪問(wèn)權(quán)限。
-s	打印默認(rèn)目錄搜索路徑。
-t	打印默認(rèn)生存時(shí)間值。
-v	以詳細(xì)格式打印默認(rèn)值。這會(huì)將標(biāo)識(shí)字符串添加到輸出中。

環(huán)境

nisdefaults使用以下環(huán)境變量：

NIS_DEFAULTS

包含默認(rèn)字符串的變量，它將覆蓋NIS +標(biāo)準(zhǔn)默認(rèn)值。默認(rèn)字符串是一系列用冒號(hào)分隔的標(biāo)記。這些標(biāo)記表示用于通用對(duì)象屬性的默認(rèn)值。合法令牌是：

ttl=時(shí)間	令牌為創(chuàng)建的對(duì)象設(shè)置默認(rèn)生存時(shí)間。時(shí)間值以nischttl命令定義的格式指定。默認(rèn)值為12小時(shí)。
所有者=ownername	指定NIS +主體所有者名稱應(yīng)擁有創(chuàng)建對(duì)象的令牌。該值的默認(rèn)值為執(zhí)行命令的主體。
group=groupname	用于指定組groupname應(yīng)該是所創(chuàng)建對(duì)象的組所有者的令牌。默認(rèn)值為NULL。
access=rights	令牌，用于指定要為創(chuàng)建的對(duì)象授予的訪問(wèn)權(quán)限集。值權(quán)限以nischmod命令定義的格式指定。默認(rèn)值為： ----rmcdr---r---

NIS_GROUP

包含本地NIS +組名稱的變量。如果名稱不完全限定，則會(huì)將默認(rèn)域附加到該名稱。

NIS_PATH

覆蓋默認(rèn)NIS +目錄搜索路徑的變量。它包含以' ： '（冒號(hào)）字符分隔的目錄的有序列表。' $ '（美元符號(hào)）字符被特殊對(duì)待。以“ $ ”結(jié)尾的目錄名稱附加了默認(rèn)域，并且“ $ ”本身被默認(rèn)域和全局根之間的目錄列表替換，該目錄至少深兩個(gè)級(jí)別。缺省NIS +目錄搜索路徑為' $ '。有關(guān)更多詳細(xì)信息，
請(qǐng)參閱NIS +中的“名稱擴(kuò)展”小節(jié)。

nisdefaults [-adghprstv]

Options

-a	Print all defaults in a terse format.
-d	Print the default domain name.
-g	Print the default group name.
-h	Print the default hostname.
-p	Print the default principal name.
-r	Print the default access rights with which new objects will be created.
-s	Print the default directory search path.
-t	Print the default time to live value.
-v	Print the defaults in a verbose format. This prepends an identifying string to the output.

Environment

nisdefaults makes use of the following environment variables:

NIS_DEFAULTS

Variable that contains a defaults string that will override the NIS+ standard defaults. The defaults string is a series of tokens separated by colons. These tokens represent the default values to be used for the generic object properties. Legal tokens are:

ttl=time	Token that sets the default time to live for objects that are created. The value time is specified in the format as defined by the nischttl command. The default value is 12 hours.
owner=ownername	Token that specifies that the NIS+ principal ownername should own created objects. The default for this value is the principal who is executing the command.
group=groupname	Token that specifies that the group groupname should be the group owner for created objects. The default is NULL.
access=rights	Token that specifies the set of access rights that are to be granted for created objects. The value rights is specified in the format as defined by the nischmod command. The default value is: ----rmcdr---r---

NIS_GROUP

Variable that contains the name of the local NIS+ group. If the name is not fully qualified, the default domain will be appended to it.

NIS_PATH

Variable that overrides the default NIS+ directory search path. It contains an ordered list of directories separated by ':' (colon) characters. The '$' (dollar sign) character is treated specially. Directory names that end in '$' have the default domain appended to them, and a '$' by itself is replaced by the list of directories between the default domain and the global root that are at least two levels deep. The default NIS+ directory search path is '$'.

Refer to the Name Expansion subsection in NIS+ for more details.
