using wc -l in loop

Hi All, I'd like to make a list members and total member from my milis using ezmlm-list. I make this script: #!/bin/bash echo Lihat user, masukan username tanpa domain read mail a=`/usr/local/bin/ezmlm/ezmlm-list /home/vpopmail/domains/domai.com/staff | grep $mail | sort ` for x1 in $a ; do echo staff $x1 done But I dont know where should I put 'wc -l' to know total of members.. Any idea ? Is there any other way beside using wc -l ? regards, -- Arie Reynaldi Zanahar reymanx at gmail.com http://www.reynaldi.or.id
