bingo Stéphane !

le "sticky bit" positionné sur /tmp/ empêche l'utilisateur root d'altérer le fichier appartenant au simple utilisateur user !

$ ls -ld /tmp/
drwxrwxrwt 13 root root 320 Dec 17 13:22 /tmp/

$ ls -l /tmp/test 
-rw-r--r-- 1 user user 0 Dec 17 13:24 /tmp/test

$ echo test | sudo tee -a /tmp/test 
tee: /tmp/test: Permission denied
test

mais il n'empêche pas sa suppression !

$ sudo rm -v /tmp/test
removed '/tmp/test'

ce qui m'a induit en erreur : désolé pour la perte de temps.

bonne fin d'année 2020, lacsaP.
