bingo St=C3=A9phane !

le "sticky bit" positionn=C3=A9 sur /tmp/ emp=C3=AAche l'utilisateur root d=
'alt=C3=A9rer le fichier appartenant au simple utilisateur user !

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

$ ls -l /tmp/test=20
-rw-r--r-- 1 user user 0 Dec 17 13:24 /tmp/test

$ echo test | sudo tee -a /tmp/test=20
tee: /tmp/test: Permission denied
test

mais il n'emp=C3=AAche pas sa suppression !

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

ce qui m'a induit en erreur : d=C3=A9sol=C3=A9 pour la perte de temps.

bonne fin d'ann=C3=A9e 2020, lacsaP.
