Shell script lecture des arguments

Bonjour,

J'ai fait un shell script qui permet de "killer" soit un user, soit un process, soit un process correspondant à un user.
quand je le lance avec les arguments suivants par example, pour "killer" le user jean et le process vi ca marche bien: sh kill_proc jean vi
Mais si je veux le lancer afin qu'il arrete plusieurs process à la fois (par example sh kill_proc jean vi|more), il n'arrete que le process vi et il ne prend pas en compte le process more. En fait concernant le 2ieme argument il ne lit que la partie qui est avant le |. Comment pourrais-je faire pour kil lise le vi et le more?
Merci
