Bonjour,
Voilàa je me pose une petite colle pour le traitement de fichier texte.
En realité il s’agit d’un fichier de configuration Cisco que je dois “parser”.
Mon fichier va ressembler à ceci quand je le recupère :
[code]Ethernet107/1/20 is down (Link not connected)

Pour l’exemple je n’ai pris que 3 interfaces 
Il faudrait que le scipt récupère en fonction de la demande les informations suivantes :
Si l’utilisateur veut voir l’interface Ethernet107/1/22 le script ne doit retourner que ceci :
Ethernet107/1/22 is down (Link not connected)
Hardware: 100/1000 Ethernet, address: a4138.7589.1957 (bia a4138.7589.1957)

et non pas mes 5000 pages de conf 
Donc pour le début il me suffit de faire un grep car l’utilisateur va saisir le nom exacte de l’interface.
Ensuite toutes les lignes, propre à cette interface sont indentés d’une tabulation, donc il suffit que je lui dise que le premier caractère est une tabulation.
Mais la ou je ne sais pas faire, c’est comment dire : ça commence à ça et ça se termine par une ligne vide.
Pour le moment j’ai donc mon début :
#Debut en trouvant le nom de l’interface
grep Ethernet107/1/20
#Milieu en disant “tant que tabulation” ou autre
#FIN en matchant la ligne de séparation
grep ^$
Malheureusement avec un grep il n’est pas possible de délimiter un paragraphe, avec awk en colonne je ne sais pas comment m’en sortir (sauf option utiles que je connais pas )
Connaissez-vous des outils pour le faire ?
Merci
