为什么PWD命令看不到当前目录?其他命令则错误

marchyc

现在我的系统用root登录后，打pwd，看不到东西，用ls scoadmin等会提示error，但是cd 进入到下级子目录的后可以使用ls命令这是怎么回事呢?

marchyc

错误代码如下
# ls
ls: . not found: No such file or directory (error 2)
# scoadmin
Error: error getting working directory name: No such file or directory
error getting working directory name: No such file or directory
    while executing
"pwd"
    invoked from within
"set currentDir         [pwd]..."
    (file "/usr/bin/scoadmin" line 2267)
