怎样让命令提示符能把路径显示完整啊？？

ecco2005

我的CentOS上只显示最后一个子目录的名字，我想显示完整，怎么办？

[root@centos zlib-1.2.3] 我的就是这样的……

我想改成这个样子 root:/usr/local/src/lamp/zlib-1.2.3

修改你的 bash 变量 PS1：
你看看现在它是什么值？
$ set | grep PS

然后根据这个说明来改：（这个说明你可以通过 $ man bash 然后 查找 PROMPTING 字串
找到）

2. PROMPTING
3.        When executing interactively, bash displays the primary prompt PS1 when it is ready to read a command, and the  secondary  prompt  PS2
4.        when it needs more input to complete a command.  Bash allows these prompt strings to be customized by inserting a number of backslash-
5.        escaped special characters that are decoded as follows:
6.               \a     an ASCII bell character (07)
7.               \d     the date in "Weekday Month Date" format (e.g., "Tue May 26")
8.               \D{format}
9.                      the format is passed to strftime(3) and the result is inserted into the prompt string; an  empty  format  results  in  a
10.                      locale-specific time representation.  The braces are required
11.               \e     an ASCII escape character (033)
12.               \h     the hostname up to the first ‘.’
13.               \H     the hostname
14.               \j     the number of jobs currently managed by the shell
15.               \l     the basename of the shell’s terminal device name
16.               \n     newline
17.               \r     carriage return
18.               \s     the name of the shell, the basename of $0 (the portion following the final slash)
19.               \t     the current time in 24-hour HH:MM:SS format
20.               \T     the current time in 12-hour HH:MM:SS format
21.               \@     the current time in 12-hour am/pm format
22.               \A     the current time in 24-hour HH:MM format
23.               \u     the username of the current user
24.               \v     the version of bash (e.g., 2.00)
25.               \V     the release of bash, version + patch level (e.g., 2.00.0)
26.               \w     the current working directory, with $HOME abbreviated with a tilde
27.               \W     the basename of the current working directory, with $HOME abbreviated with a tilde
28.               \!     the history number of this command
29.               \#     the command number of this command
30.               \$     if the effective UID is 0, a #, otherwise a $
31.               \nnn   the character corresponding to the octal number nnn
32.               \\     a backslash
33.               \[     begin a sequence of non-printing characters, which could be used to embed a terminal control sequence into the prompt
34.               \]     end a sequence of non-printing characters
36.        The  command number and the history number are usually different: the history number of a command is its position in the history list,
37.        which may include commands restored from the history file (see HISTORY below), while  the  command  number  is  the  position  in  the
38.        sequence  of commands executed during the current shell session.  After the string is decoded, it is expanded via parameter expansion,
39.        command substitution, arithmetic expansion, and quote removal, subject to the value of the promptvars shell option (see  the  descrip-
40.        tion of the shopt command under SHELL BUILTIN COMMANDS below).

你要的效果可以这样改：
$ PS1='[\u:`pwd`]\$ '

要长久有效的话就把它添加到: .bashrc 文件中。
添加的行：
export PS1='[\u:`pwd`]\$ '
