Je suis nouveau sur Ubuntu. J'utilise le bureau 13.10.
Je voulais définir des alias système et une invite personnalisée pour bash. J'ai trouvé cet article:

Suivant les conseils de cet article, j’ai créé /etc/profiles.d/profile_local.sh. Il appartient à root et possède les autorisations de 644, tout comme les autres scripts de cet emplacement:
[email protected]:/etc/profile.d# ll
total 28
drwxr-xr-x 2 root root 4096 Mar 23 08:56 .
drwxr-xr-x 135 root root 12288 Mar 23 09:15 ..
-rw-r--r-- 1 root root 660 Oct 23 2012 bash_completion.sh
-rw-r--r-- 1 root root 3317 Mar 23 07:36 profile_local.sh
-rw-r--r-- 1 root root 1947 Nov 23 00:57 vte.sh
J'ai également confirmé que / etc / profile appelle /etc/profile.d. Il contient ce bloc de code:
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
Lors de la connexion, il ne semble pas que le script personnalisé profile_local.sh que j'ai créé soit identifié. Toutefois, si, après la connexion, je source /etc.profile.d/profile_local.sh, le comportement attendu, mes alias personnalisés et mes invites personnalisées me sont fournis.
Qu'est-ce que je fais mal?
