提问by dicaprio
I did a search in this repository and I didn't find any similar questions or may be my search was incorrect.
我在这个存储库中进行了搜索，但没有找到任何类似的问题，或者可能是我的搜索不正确。
I have this problem in my clients environment, a custom application is creating directories with an environmental variable "$SRCDIR" and "$HOME" and the dir's where these are created , itself is the HOME dir path. if I say rm -rf $HOMEthen all the files and subdir's under $HOME which is current directory will be deleted . How do I delete these unwanted directories.
我在我的客户端环境中遇到了这个问题，一个自定义应用程序正在创建带有环境变量“$SRCDIR”和“$HOME”的目录以及创建这些目录的目录，它本身就是 HOME 目录路径。如果我说，rm -rf $HOME那么当前目录 $HOME 下的所有文件和子目录都将被删除。如何删除这些不需要的目录。
-rw-r--r-- 1 grp domain users 418051450 Apr 18 18:09 $SRCDIR
-rw-r--r-- 1 grp domain users 418051450 Apr 18 18:09 $HOME
Also some directories are junk characters as below example.
还有一些目录是垃圾字符，如下例所示。
-rwxr-xr-x 1 grp domain users 0 Feb 7 2106 ??????w?O???*????_6??t??ó??>?tP????|?C
How do I delete them ?

For the junk names, it would be easiest to construct a wildcard that would catch only them. Select a readableportion of the name (e.g. the _6substring) and wrap it in asterisks. First try it out:
对于垃圾名称，最容易构建一个只能捕获它们的通配符。选择名称的可读部分（例如_6子字符串）并将其用星号括起来。先试试看：
ls *_6*
If it lists onlythe junk name, proceed to delete it:
如果它列出只有垃圾的名字，继续将其删除：
rm *_6*
If it lists other names as well, try to make the wildcard more specific, using other readable characters in the name:
如果它还列出了其他名称，请尝试使通配符更具体，在名称中使用其他可读字符：
ls *w*_6*tP*N*x*
Proceed until you've found a wildcard that would match only unwanted files.
继续操作，直到找到仅匹配不需要的文件的通配符。

Just escape the dollar symbol. Try like this-
只是逃避美元符号。试试这样-
rm -rf $HOME
Same with even the ?symbol.
甚至?符号也一样。

if you create a directory like --rw-r-r--. to delete this file do the following
rm -rf ./--rw-r-r--
如果你创建一个像--rw-rr--这样的目录。要删除此文件，请执行以下操作
rm -rf ./--rw-r-r--

You can try rm -rf '$HOME' '$SRCDIR' , as the single quotes would prevent the expansion of the shell variables. tried with bash and ksh.
您可以尝试 rm -rf '$HOME' '$SRCDIR' ，因为单引号会阻止 shell 变量的扩展。尝试使用 bash 和 ksh。
