I am using MINIX 1.2 to teach the OS course and a student
wrote the following script which does not terminate. I can
not figure out why? Any ideas will be appreciated.
1	#script to find the path to a command
2	#usage: where <command>
3	#
4	if test $# -ne 1; then
5	   echo "Usage: $0 <command>
6	   exit 1
7	fi
8
9	dir="/bin  /usr/bin"
10	for d in $dir; do
11	   list="`ls $d`"
12	   for name in $list; do
13		if test $1 = $name; then
14		   echo $d/$name
15		fi
16	   done
17	done
18	exit 0

If one puts an echo "" between lines 16 and 17 it works
correctly.
