Have you tried using the passwd -e option?

it's a foreach cicle

Code:
foreach i {`cat list`}
sed "|$i|s|/bin/ksh|/compte_bloque|" /etc/passwd >> /etc/passwd.new
end

Edit: I think I hit post reply too soon. Given the subject and the original requirement ... what's the problem?

First comment:
this is [t]csh syntax - don't use csh for scripting,
see this for more.

Second: use usermod (with another shell):

Code:
while IFS= read -r; do 
  usermod -s /your/shell "$REPLY" 
done<list

If read -r raises an error, remove the -r switch.

If you cannot use usermod:

Code:
awk >/etc/passwd.new -F: 'NR == FNR { u[$1]; next }
$1 in u { $NF = "/compte_bloque" }
1' OFS=: list /etc/passwd

Use nawk or /usr/xpg4/bin/awk on Solaris.

Sorry,
I don't understand awk solution . More over, I obtain an error :

awk: (FILENAME=list FNR=1) fatal: attempt to use array `u' in a scalar context

thanks for yours reply
