Lecture de script

debianhadic · Février 20, 2016, 3:23pm

N’étant pas un spécialiste des scripts je vous passe celui de hylafax pour la réception.
Ma question est :
"Ou se trouve la partie correspondant à la création du fichier fax0000?.tif sachat que le ‘?’ est un int de type auto (ou counter suivant vos habitudes) ?"
Je voudrais assigner le chmod 666 au fichier généré automatiquement, pour qu’il soit lisible depuis mes partages SAMBA.

Si une méthode plus “debian” existe je suis preneur.

bonsoir,
je vois pas là comme ça au premier coup d’oeil … Donnes nous plutôt une phrase prise dans ce fichier pour qu’on situe le bloc où elle intervient …
De plus, tu ne pourras pas appeller un chmod dans ce script vu qu’à mon avis, il s’exécute pas en root … (mais il y a une solution).

stonfi · Février 20, 2016, 3:23pm

salut,

FILENAME=`echo $FILE | $SED -e 's/\.tif//' -e 's/recvq\///'`

C’est quoi ton soucis en question ?

mattotop · Février 20, 2016, 3:23pm

il doit y avoir quelquechose à faire avec ulimit sur l’environnement du compte utilisateur sous lequel tourne hylafax (c.à.d. sans doute, l’user hylafax).

[quote=“stonfi”]salut,

FILENAME=`echo $FILE | $SED -e 's/\.tif//' -e 's/recvq\///'`

C’est quoi ton soucis en question ?[/quote]

Bon c’est bien ce que je pensais, en gros la commande echo créer le fichier et le résultat, donc le nom du fichier est stocké dans la variable FILENAME, ok?

Au passage qu’est-ce que le ‘`’ ?

le fichier créé à ce moment la est du type rw------- donc avec les droits root ceci n’implique pas que c’est root qui exécute la commande ?

à la suite de cette commande je ne peux pas faire un :

`echo chmod 666 $FILENAME` ?

usinagaz · Février 20, 2016, 3:23pm

Ah ben oui peut-être que c’est en root alors, ou ça dépend du masque par défaut du repertoire où se crée le fichier, ou bien encore du bit (je sais plus) ‘s’ du repertoire où il est créé …
Bon, si la commande renomme ne effet le fichier $FILE en $FILENAME en modifiant l’extension (il me semble), c’est un chmod 666 $FILENAME, si par contre $FILENAME ne contient qu’une variable string, que le fichier existe en fait toujours sous $FILE, ben c’est chmod 666 $FILE.
tu rajoutes cette ligne au moment où le fichier se crée, ça va pas te casser la machine et tu vois …
’' ce genre de signe signifie qu'il faut executer ce qui se trouve entre comme une commande `
