How to find and list all the symbolic links created for a particular file?

Here is an example:

find -L /dir/to/start -xtype l -samefile ~/Pictures

or, maybe better:

find -L /dir/to/start -xtype l -samefile ~/Pictures 2>/dev/null

to get rid of some errors like Permission denied, Too many levels of symbolic links, or File system loop detected which find throws them when doesn't have the right permissions or other situations.

• -L - Follow symbolic links.

• -xtype l - File is symbolic link

• -samefile name - File refers to the same inode as name. When -L is in effect, this can include symbolic links.

Notes:

• Use lowercase L in -xtype l, not the digit 1.
• On macOS / Darwin, -xtype is -type.

Very simple, use option -lname:

find / -lname /path/to/original/dir

From man find:

-lname pattern
       File is a symbolic link whose contents match shell pattern pattern.  The
       metacharacters do not treat `/' or `.' specially.  If the -L option or the
       -follow option is in effect, this test returns false unless the symbolic link
       is broken.

Note: Remember that symbolic links could be anywhere, which includes a remote system (if you’re sharing files), so you may not be able to locate them all.
