[PERL ]Tri d'un tableau 2D [Résolu]

je vous remercie pour vos réponse.

l'instruction suivante :
my @tri = sort { $a->[2] <=> $b->[2] } @tab;

marche torp bien.

Salut,

il suffit de trier selon le champ concerné (si nombre utilise <=> , si chaine de caractère utilise cmp )

voici une exemple

#!/usr/bin/perl
#
use warnings;use strict;

my @tab = (
           ["lami20j","x",1000,1000,"lami20j,,,","/home/lami20j","/bin/bash"],
           ["mysql","x",104,112,"MySQL Server,,,","/var/lib/mysql","/bin/false"],
           ["yann","x",1001,1001,"","/home/yann","/bin/bash"],
           ["sshd","x",108,65534,"","/var/run/sshd","/usr/sbin/nologin"],
           ["smmta","x",109,113,"Mail Transfer Agent,,,","/var/lib/sendmail","/bin/false"],
           ["smmsp","x",110,114,"Mail Submission Program,,,","/var/lib/sendmail","/bin/false"],
           ["bind","x",111,115,"","/var/cache/bind","/bin/false"],
           ["postfix","x",112,117,"","/var/spool/postfix","/bin/false"],
           ["papa","x",1002,10001,"","/home/papa","/bin/bash"],
           ["maman","x",1003,10001,"","/home/maman","/bin/bash"],
           ["ftp","x",113,65534,"","/home/ftp","/bin/false"],
           ["uml-net","x",114,119,"","/home/uml-net","/bin/false"],
           ["saned","x",115,120,"","/home/saned","/bin/false"],
           ["c","x",1004,1004,"","/home/c","/bin/sh"],
           ["cristi","x",1005,1005,"","/home/cristi","/bin/bash"],
           ["invite","x",1006,1006,"","/home/invite","/bin/bash"],
           ["clamav","x",116,121,"","/var/lib/clamav","/bin/false"],
          );

my @tri = sort { $a->[2] <=> $b->[2] } @tab; # tri selon le champ 3
print "@$_\n" for @tri;
__END__

Ce qui est intéressant c'est la possibilité de faire un tri sur un champ calculable
Tu peux aussi utiliser plusieurs critères en cas d'égalité. Par exemple si le champ 3 est le même tu peux trier selon un autre champ

Et le résultat
