The above is mainly -i option to indicate inode, or ls -i .

2. Delete documents based on inode number

For example, files such as "-d" and "-H" in the above directory are created under abnormal circumstances. It is inconvenient to delete them directly by name. You can delete them by specifying inode

2.1 Delete method 1-find front

Such as delete the "-d" file
find . -inum 1328244 -exec rm -i {} \;
If you don't need confirmation, just delete it (the "-H" file above):
find . -inum 1328240 -exec rm -if {} \;

2.1 Delete method 2-find post

 rm `find . -inum 1328244`

Similarly, since we can get the file name according to the find command, we can also perform other operations on it:

 # 查看文件类型
[niewj@niewj ~]$ file `find . -inum 1449101`
./sf_down: directory

# 列出文件详情
[niewj@niewj ~]$ ls -l  `find . -inum 1449101`
