I have a file named file.ext. I create an symbolic link to this file named file_symlink.ext in other folder.

When I modify file.ext directly (without opening the file via the symbolic link), the symbolic link is transformed to an effective file with the old version.

Is that normal?

I would like the symbolic link to always point to the real file, but I can't use alias because LaTeX does not accept working with aliases.

Is there any solution?

It is the last but one file.

colas-3:sources colas$ ls -li

    With which application do you edit file.ext? And why can't you run LaTeX directly on the file? – nohillside Aug 11 '18 at 16:17

    And I have some troubles understanding "the symbolic link is transformed to an effective file with the old version", can you add some output of ls -li demonstrating this? – nohillside Aug 11 '18 at 16:18

    I edit file.ext with TeXShop. Actually, I include the files with the symlinks. – Colas Aug 11 '18 at 16:19
  • Strangely, I cannot reproduce the issue... – Colas Aug 11 '18 at 16:26
  • @nohillside It came again. I have updated the question. – Colas Aug 11 '18 at 16:38

    So TeXShop seems to rewrite included files somehow. Not sure you can prevent this from happening, I would probably just run LaTeX directly in the Dropbox folder. – nohillside Aug 11 '18 at 16:40

    How are you creating the symlink? Try this command: ln -s /Users/colas/Dropbox/Maths/Maths_2018_2019/C. Exercices, DM, Interros/7. Relations/exercices/exercices_relations.tex /some/other/directory/exercises_relations.tex – Allan Aug 11 '18 at 16:57

    I use an app called SymbolicLinker – Colas Aug 11 '18 at 17:13

    @nohillside Maybe it is related but while I edit the file with TeXShop an alert pops: "Your file has been modified by another app. Do you really wish to save?" – Colas Aug 11 '18 at 17:37
