考虑使用任意子目录的某个目录的固定绝对路径:
/full/path/to/fixed/directory
/full/path/to/fixed/directory/first_subdirectory
/full/path/to/fixed/directory/first_subdirectory/second_subdirectory
以及上述directory
的不是子目录的任意其他目录:/other/path
我希望在终端中看到以下内容:
user@host: .../directory$
user@host: .../directory/first_subdirectory
user@host: .../directory/first_subdirectory/second_subdirectory
user@host: /other/path$
其中最后一行是典型案例,但其他行代替
user@host: /full/path/to/fixed/directory$
user@host: /full/path/to/fixed/directory/first_subdirectory
user@host: /full/path/to/fixed/directory/first_subdirectory/second_subdirectory
如何实施?
P.S。路径可以包含空格。

我会使用特殊的PROMPT_COMMAND
var。例如:
[the-old-prompt] $ cat ps1
g_theSpecialDir=/tmp/im/the/magic/directory
g_pwd=
_prompt_cmd()
{
if [[ $PWD/ == $g_theSpecialDir/* ]]; then
g_pwd=.../${g_theSpecialDir##*/}${PWD#$g_theSpecialDir}
else
g_pwd=$PWD
fi
}
PROMPT_COMMAND=_prompt_cmd
PS1='[\u@\h $g_pwd] $ '
[the-old-prompt] $ source ./ps1
[whjm@localhost /tmp] $ cd /tmp/im/the/magic/directory/
[whjm@localhost .../directory] $ cd dir1/
[whjm@localhost .../directory/dir1] $ cd dir2/
[whjm@localhost .../directory/dir1/dir2] $ cd /tmp/
[whjm@localhost /tmp] $
您可以在Bash manual中找到PROMPT_COMMAND
var。此解决方案使您可以在提示中包含您喜欢的任何内容。
