如何定制提示符

aseyt

请问在SunOS下如何定制提示符？

比如我在#提示符下进入到ASE这个目录，则系统提示符为#ASE>;

我在.profile 文件中export PS1，PS1为$PWD，好像不能用，大家知道的能告诉我吗，先谢了。

问题太简单没人理吗？:em12:

在SCO UNIX下export PS1='$PWD>;'可以用，SunOS下环境变量不是这个$PWD吗？:em12: :em12:

不知道的也进来讲一声，还没等到答案连贴子都快掉底看不见了。

Changing Your Command Prompt
The syntax you use to change your command prompt depends on what shell you are
using.
Bourne, Bourne Again, Korn, and Z Shells
In the Bourne, Bourne Again, Korn, and Z shells, use the PS1 command to redefine
your command prompt. The following are three examples:

To set the prompt to a colon (:), followed by a space, type the following command.
PS1=": "

To create a prompt that consists of your machine name, followed by a colon and a
space, type the following command.
PS1="‘hostname‘: "

To set the prompt to your machine name, followed by your login name in braces
{}, a colon, and a space, type the following command
PS1="‘hostname‘{‘logname‘}: "
Type any of the previous examples to change your current command prompt. This
change applies until you change your command prompt again or log out.
If you want to make your changes more permanent, add one of the previous examples
(or a prompt of your own creation) to your user profile file. If you follow this
guideline, the prompt you specify appears each time you log in in or start a new shell.
C and TC Shells
For the C and TC shells, you personalize your command prompt with the set
prompt command. The following are three examples:

To set the prompt to a percent sign followed by a space, type the following
command.
example% set prompt="% "

To create a prompt that consists of your machine name, followed by the history
number of the command (hostname1, hostname2, hostname3, and so on), followed by
a colon, type the following command.
example% set prompt="‘hostname‘\!: "

To set the prompt to your machine name, followed by your login name in braces, a
colon, and a space, type the following command.
example% set prompt="‘hostname‘{‘logname‘}: "
Type any of the previous examples to change your current command prompt. This
change applies until you change your command prompt again or log out.
If you want to make your changes more permanent, add one of the previous examples
(or a prompt of your own creation) to your user profile file. If you follow this
procedure, the prompt you specify appears each time you log in or start a new shell.

简单的说，Bourne Shell不支持$PWD，换成KSH就可以了。在Bourne Shell和KSH下，都可以用`pwd`，但Bourne Shell不能实现动态的目录显示。

懂了，在本站论坛上的贴子都讲的不够清楚，我的SHELL环境只有SH，KSH是不支持PS1的，楼上的KSH我试过了，不错，是个静态的，可惜了。
非常感谢MELONM和xingshb的帮助。
