[awk] Afficher le FILENAME une fois par fichier puis afficher le mot suivant des occurrences dans le contenu

**guenoel** · 05/08/2020, 18h40

Bonjour !

J'ai un dossier titi contenant plusieurs dossiers nommés toto_tata. Chaque dossier contient (entre autres) un fichier backtrace.log

Je souhaite créer un fichier .csv avec une seule ligne par fichier backtrace.log qui devrait ressembler a ça:

toto1;tata1;mot suivant l'occurrence1;mot suivant l'occurrence2;mot suivant l'occurrence3
toto2;tata2;mot suivant l'occurrence1;mot suivant l'occurrence2;mot suivant l'occurrence3
etc...
(autant de lignes que de fichiers backtrace.log - pas de chiffre après toto ou tata en vrai

)

Pour le moment ce code:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
 
for fn in /CHEMIN/VERS/titi/*/*.log; do
awk -F'[ \\+]' '{NR==1; OFS=";"
  for (i=1;i<=NF;i++) {
        if ($i=="RIP:"){print FILENAME,$(i+1)>>"/CHEMIN/VERS/titi/export.csv"};
		}}' $fn
done

...me donne ça:
CHEMIN/VERS/titi/toto_tata1;mot suivant l'occurrence1
CHEMIN/VERS/titi/toto_tata1;mot suivant l'occurrence2
CHEMIN/VERS/titi/toto_tata1;mot suivant l'occurrence3
CHEMIN/VERS/titi/toto_tata2;mot suivant l'occurrence1
CHEMIN/VERS/titi/toto_tata2;mot suivant l'occurrence2
CHEMIN/VERS/titi/toto_tata2;mot suivant l'occurrence3
...

(pas de chiffre après toto_tata en vrai

)

...et ce code:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
for fn in /GNOC/Kernel_panic/Imports/*/*.log; do
printf $fn | awk -F'[_/]' '{print $(NF-2)";"$(NF-1)}'
done

me donne:

toto1;tata1
toto2;tata2
etc...

Sinon avec print ARGV[1] ce code:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
for fn in /CHEMIN/VERS/titi/*/*.log; do
awk 'BEGIN{ORS=";"; print ARGV[1]}' $fn
done

...me donne:
/CHEMIN/VERS/titi/toto_tata1;/CHEMIN/VERS/titi/toto_tata2;/CHEMIN/VERS/titi/toto_tata3;etc...

J'ai essayé de mettre un print ARG[1] avant la boucle de la commande awk mais j'arrive pas.

(Vous avez compris, je suis un newbie!)

Bonjour,

la boucle shell est inutile, et par substitution successives, tu dois pouvoir retrouver le nom du répertoire au-dessus du backtrace en traitement :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk '{...}' /chemin/titi/*/backtrace.log

**guenoel** · 05/08/2020, 19h14

Ah oui effectivement la boucle en bash est pas nécessaire !

Comment re-traiter un print FILENAME sans utiliser de tube comme dans cet exemple ?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
for fn in /GNOC/Kernel_panic/Imports/*/*.log; do
printf $fn | awk -F'[_/]' '{print $(NF-2)";"$(NF-1)}'
done

**N_BaH** · 05/08/2020, 19h45

je ne comprends pas la question.

**Flodelarab** · 05/08/2020, 20h42

Bonjour

Est-ce qu'on peut avoir le vrai but réel ? Non, parce que, là, j'ai l'impression que tu réinventes grep.

Soit un fichier rip0.txt :

blablabla RIP blablabla encore RIP
et puis RIPattaché avant attachéRIPaumilieu et aprèsRIP
et puis RIP
et enfin
RIP

Et des fichiers dérivés :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

for ((i=1;i<6;i++));do sed "${i}d" rip0.txt > "rip${i}.txt";done

La commande pour compter le nombre de RIP dans chaque fichier est la suivante :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
$ grep -Ho RIP rip* | uniq -c
      7 rip0.txt:RIP
      5 rip1.txt:RIP
      4 rip2.txt:RIP
      6 rip3.txt:RIP
      7 rip4.txt:RIP
      6 rip5.txt:RIP

Et la commande pour compter le nombre de mot RIP dans chaque fichier est la suivante :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
$ grep -Ho '\<RIP\>' rip* | uniq -c                                                                                                                                                                                                                             
      4 rip0.txt:RIP
      2 rip1.txt:RIP
      4 rip2.txt:RIP
      3 rip3.txt:RIP
      4 rip4.txt:RIP
      3 rip5.txt:RIP

Ce qui est bien plus simple que le code du début de discussion.

salut,

Je souhaite créer un fichier .csv avec une seule ligne par fichier backtrace.log (...)

c'est pas clair du tout, par exemple j'ai du mal à comprendre à quoi correspondent totoX et tataY si il n'est question que des fichiers nommés "backtrace.log"
par ailleurs :

Envoyé par guenoel

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

(...) /GNOC/Kernel_panic/Imports/*/*.log (...)

on en déduit assez simplement que les logs en question sont des backtraces de kernel panic (et donc les RIP ce sont les adresses 64b où le kernel est censé s'être vautré)

or dans ces logs on trouve des lignes avec l'occurrence "RIP:" qui peuvent avoir cette tête là :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2

4
[exception RIP: intel_idle+213]
[exception RIP: unknown or invalid address]
RIP: 0010:[<ffffffff81318bc4>] [<ffffffff81318bc4>]
RIP: ffffffff816ab6a5  RSP: ffff8b00fb16fe20  RFLAGS: 00000046

pas évident dans ces conditions de savoir ce que tu cherches précisément à extraire

alors de ce que j'ai compris/extrapolé, et en admettant :

que totoX corresponde au dernier répertoire (le sous-répertoire dans Imports/ donc)
que tataX corresponde au nom du fichier de log, sans l'extension (donc "backtrace" dans le cas de backtrace.log)
qu'il s'agisse pour chaque occurrence de RIP: de récupérer l'adresse 64b hexa qui suit et les concaténer afin de ne former qu'une seule ligne par fichier de log du type:
Code : Sélectionner tout - Visualiser dans une fenêtre à part
```
totoX;tataY;ffffffff816ab6a5;ffffffff81318bc4;...
```
que tu utilises GNU Awk (sinon Samar Shrapa)

on peut envisager un bout de code du genre :

Code script.awk :

/RIP: [0-9a-f]{16}/ {             # specifique GNU Awk (regex quantifier)
   for (i = 1; i < NF; i++) {
      if ($i == "RIP:") {
         line = line ";" $(i+1)
         break
      }
   }
}
 
ENDFILE {                        # specifique GNU Awk
   n = split(FILENAME, tab, "/")
   gsub(/\.log/, "", tab[n])     # on enleve l extension .log du nom de fichier
   prefix = tab[n-1] ";" tab[n]  # prefixe de la forme "sous-repertoire;fichier"
   print prefix line
   line = ""
}

qu'on pourra invoquer via gawk -f script.awk /GNOC/Kernel_panic/Imports/*/*.log.

**guenoel** · 07/08/2020, 18h23

Voila le truc tordu qui me satisfait (presque) il faudrait juste enlever les 4 premiers caractères de chaque ligne en plus et c'est fini

Code :

printf $fn | awk -F'[_/]' 'ORS=";"{print $(NF-2)";;;"$(NF-1)>>"/CHEMIN/extract/export.txt"}'
awk -F'[ \\+]' '{NR==1;ORS=";"
  for (i=1;i<=NF;i++){
        if ($i=="RIP:") print $(i+1)>>"CHEMIN/extract/export.txt"
		else if ($i=="erreur2") print "erreur2">>"CHEMIN/extract/export.txt"
		else if ($i=="erreur3") print "erreur3">>"CHEMIN/extract/export.txt"}
		        }
	END{ORS="";print "\n">>"CHEMIN/extract/export.txt"
	   }' $fn
done

Je vais étudier vos réponses lundi ! Merci !

salut,

c'est le dossier qui s'appelle toto_tata et le fichier qui est dedans s'appelle toujours backtrace.log (toto c'est le No de machine et tata le timestamp)

Tout a fait ! Dans mon cas les formes des erreurs sont du type :
[xxxxxxx.xxxxxx] RIP: xxxx:nom_erreur+0x4x/0x1xx
[xxxxxxx.xxxxxx] RIP: xxxx:0x7xxxxxxxxxx
[xxxxxxx.xxxxxx] RIP: nom_erreur+0x4x/0x1xx RSP: xxxxxxxxxxxxx

je constate à présent que la dernière ligne contenant "RIP:" semble me donner la bonne erreur à chaque fois

Là, du coup, je me suis mal fait comprendre ! Il faudrait peut-être que j'ai un "print $(i+1)" dans la boucle pour sortir le nom_erreur à l'écran

**guenoel** · 21/08/2020, 16h08

Du coup avec les nouvelles données : Je cherche a modifier le code suivant pour ne retenir que l'erreur à la suite de la derniere occurence "RIP:"

**guenoel** · 27/08/2020, 14h06

Comme on aurait pu le prévoir, j'ai rencontré le cas ou la dernière occurence "RIP:" précède une adresse mémoire (genre "0x876308741234") au lieu d'un message d'erreur.
J'ai donc décidé de chercher une solution pour:
_ Supprimer les champs contenants une adresse memoire "0x............" (fait !)
_ Supprimer les quatres chiffres précedent ":" ainsi que ":" lui-même (Fait !)
_ Supprimer les champs contenants "mwait_idle" (Fait !)
_ Supprimer les doublons de champs dans une même ligne (là je sens que je vais avoir besoin d'aide !)

salut,

perso à ce stade je sais plus ce que contient le fichier $file2 ni ce que tu veux obtenir exactement

par ailleurs ton code est pas mal cradingue, il y a des tournures que tu pourrais éviter
par exemple cat fichier | grep pattern | awk '{action}' qui se troque facilement pour un awk '/pattern/ {action}' fichier
et il y a fort à parier qu'on pourrait regrouper toute ta série de commandes en un unique script awk, perl, python, ... ou en tous cas une version allégée/plus propre

ce serait bien plus simple si tu donnais un exemple concret de fichier en entrée et le résultat exact attendu.

**guenoel** · 01/09/2020, 12h05

Exemple d'un fichier en entrée (il y en a plusieurs - le résultat doit être d'une ligne par fichier):

Il se peut qu'il y ait plusieurs codes erreur différents, dans ce cas il faudra garder les codes erreur différents sans doublons sur une même ligne.

salut,
par ailleurs ton code est pas mal cradingue, il y a des tournures que tu pourrais éviter
par exemple cat fichier | grep pattern | awk '{action}' qui se troque facilement pour un awk '/pattern/ {action}' fichier

En fait je l'avait écrit comme ca

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk -F'[ \\+]' 'ORS=";";/RIP/ {print $3>>"/GNOC/Kernel_panic/Imports/extract/export.txt"}' $fn

mais il parcourrait tous les fichiers en les affichant à l'écran et j'aimais pas . Est-ce qu'il y a une commande comme : print $3>>fichier qui envoie dans le fichier sans affichage à l ecran ?

et il y a fort à parier qu'on pourrait regrouper toute ta série de commandes en un unique script awk, perl, python, ... ou en tous cas une version allégée/plus propre

Je vais bientôt commencer une formation Python. Comme tu l'as surement remarqué, j'ai très peu codé dans ma vie.

**Flodelarab** · 01/09/2020, 14h02

Tu as fait une erreur. L'expression "ORS=..." est prise comme une condition puisqu'elle n'est pas dans un bloc. Donc ta ligne est affichée puisque l'affectation est vraie.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$ awk 'ORS=";"; /toto/{print "tata";}' <<<toto
toto;tata;$

**guenoel** · 01/09/2020, 16h57

En entrée on a: "toto"
la condition c'est: si on a: "toto" alors: affiche "tata"
séparateur d'enregistrements en sortie: ";"
Par quel mystère que j'ai pas compris le résultat est : "toto;tata;"
Dans ma compréhension incomplète ça devrait afficher que: "tata;"

Quelle serait la bonne syntaxe pour que ORS=";" soit pris pour un paramètre et pas une condition ?

**Flodelarab** · 01/09/2020, 17h24

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk 'condition{instructions;} condition{instructions;} condition{instructions;} condition{instructions;}' fichier

Dans ton cas, l'affectation d'ORS est une condition. Sinon, tu aurais fait :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk 'BEGIN{ORS=";";} ...' fichier

ou

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk -vORS=';' '...' fichier

Donc à chaque ligne, il va affecter ORS. Comme c'est vrai, elle fait l'instruction. Comme il n'y a pas d'instruction, elle fait l'instruction par défaut. Et l'instruction par défaut est l'affichage de la ligne. Puis le script continue avec le deuxième groupe. La condition est que la ligne contienne toto, ce qui est vrai. Et il affiche tata.

Quelle serait la bonne syntaxe pour que ORS=";" soit pris pour un paramètre et pas une condition ?

La réponse est au-dessus.
J'ajoute que si tu avais écris {ORS=";";}, il aurait affecté pour chaque ligne. Ce qui n'est pas nécessaire. NOTE: là, c'est la condition qui est absente. Donc la condition est vraie, les instructions se font pour toutes les lignes.

D'où certains scripts avec "1". "1" est est vrai, donc la condition est vraie. Et l'action (par défaut) est l'affichage de la ligne.
awk '1' fichier affiche ton fichier.

Enfin, ce n'est pas forcément une mauvaise chose de mettre une action dans la condition. L'exemple suivant supprime en sortie les lignes redondantes d'un fichier d'entrée :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

awk '!vu[$0]++' fichier

Effectivement ca marche beaucoup mieux ! Merci !

Il me reste plus qu'a trouver le code qui permet non pas de supprimer des LIGNES redondantes mais des CHAMPS redondants sur une même ligne. (pas des champs redondants sur des lignes différentes)
