Difficile de trouver un titre correspondant \u00e0 la probl\u00e9matique.
\nIl se trouve que lorsque vous tapez la commande suivante dans un shell, vous obtenez le r\u00e9sultat ci-dessous:<\/p>\n

debian:~\/tmp# ls
\ntest1.txt test deux.txt test_trois.txt
\ndebian:~\/tmp# for i in $(find . -name “*.txt”); do echo $i; done
\n.\/test1.txt
\n.\/test_trois.txt
\n.\/test
\ndeux.txt\n<\/div>\n

Comme on peut le constater, “test deux.txt” ayant un espace dans son nom, il est affich\u00e9 sur deux lignes dans notre r\u00e9sultat au lieu d’une seule ligne.<\/p>\n

Pour fixer ce probl\u00e8me, il suffit de modifier la variable IFS<\/a> qui d\u00e9termine le s\u00e9parateur, puisque par d\u00e9faut le s\u00e9parateur va \u00eatre un espace.
\nPour se faire nous devons mettre notre commande dans un script :<\/p>\n

#!\/bin\/bash
\n# on demande \u00e0 ce que le s\u00e9parateur soit sur le retour \u00e0 la ligne
\nIFS=’
\n‘
\nfor i in $(find . -name “*.txt”); do
\n echo $i;
\ndone<\/div class=\"code\">\n

Le r\u00e9sultat de l’ex\u00e9cution de notre script :<\/p>\n

debian:~\/tmp# .\/script.sh
\n.\/test1.txt
\n.\/test_trois.txt
\n.\/test deux.txt<\/div>\n
