How to move one directory back in unix / linux when path contains symbolic links?
提问by manav m-n
I have created a symbolic link to a deeply nested directory. Using symbolic link i can move to that directory from my home directory. I want to move one directory back from the target directory but the shell comes back to the home directory.
我创建了一个指向深层嵌套目录的符号链接。使用符号链接，我可以从我的主目录移动到该目录。我想将一个目录从目标目录移回，但 shell 返回到主目录。
[root@pe1800xs ~]# pwd
/root
[root@pe1800xs ~]# mkdir -p abc/def/ghi/jkl/mno/pqr
[root@pe1800xs ~]# ln -s abc/def/ghi/jkl/mno/pqr/ xyz
[root@pe1800xs ~]# cd xyz
[root@pe1800xs xyz]# pwd
/root/xyz
[root@pe1800xs xyz]# pwd -P
/root/abc/def/ghi/jkl/mno/pqr
[root@pe1800xs xyz]# cd ..
[root@pe1800xs ~]# pwd
/root
What I want to achieve is that when I do cd..in pqrdirectory the shell should come to mnodirectory.
我想要实现的是，当我cd..在pqr目录中执行时，shell 应该进入mno目录。

You must use
你必须使用
cd -P xyz
to enter into that directory to follow the original structure of folders, then you can move as you wish because you have resolved the link to the real path.
进入该目录以遵循文件夹的原始结构，然后您可以随意移动，因为您已解析到真实路径的链接。
