The issue of deleting all other files (clips) outside of the specified file in "Linux" Linux

There is an issue today that you want to delete files other than the specified file (folder). The way it was found on the Internet.

You need to do this in the current folder:

Rm-rf! (keep) #删除keep文件之外的所有文件

Rm-rf! (KEEP1|KEEP2) #删除keep1和keep2文件之外的所有文件

　　

There's a big pit under Ubuntu14.04, Keep1 and keep2 with "|" Never leave spaces between them, that is! (Keep1 | keep2). This will delete all the files in the current folder.

It should be written like this (KEEP1|KEEP2).

Specific reasons unknown, and so slowly looking for. Again later to add.
