符号链接：查找链接到该文件的所有文件

Question

Hallo all, I need to do this in linux:

• Given: file name 'foo.txt'
• Find: all files that are symbolic links to 'foo.txt'

How to do it? Thanks!

Answer 1

It depends, if you are trying to find links to a specific file that is called foo.txt, then this is the only good way:

find -L / -samefile path/to/foo.txt

On the other hand, if you are just trying to find links to any file that happens to be named foo.txt , then something like

find / -lname foo.txt

or

find . -lname \*foo.txt # ignore leading pathname components

Answer 2

Find the inode number of the file and then search for all files with the same inode number:

$ ls -i foo.txt
41525360 foo.txt

$ find . -follow -inum 41525360

Alternatively, try the lname option of find , but this won't work if you have relative symlinks eg a ->../foo.txt

$ find . -lname /path/to/foo.txt

Answer 3

I prefer to use the symlinks utility, which also is handy when searching for broken symlinks. Install by:

sudo apt install symlinks

Show all symlinks in current folder and subfolders:

symlinks -rv .

• -r : recursive
• -v : verbose (show all symlinks, not only broken ones)

To find a specific symlink, just grep :

symlinks -rv . | grep foo.txt
