Without changing the way your program currently works, try:

Code:

PATH1=/home/data1
PATH2=/home/data2
PATH3=/home/data3
PATH4=/home/data3


for path in $PATH1 $PATH2 $PATH3 $PATH4; do
  for i in $(seq 1 10); do

    p=$path/msg00"${i}"

    n=`ls -lrt $p | wc -l`
 
    echo  " $p ==$n"
  done
done

That said, there are *much* better ways to do this.

For example (requires "find" with maxdepth option, and off the top of my head and untested, so no guarantees):

Code:

PATH1=/home/data1
PATH2=/home/data2
PATH3=/home/data3
PATH4=/home/data3 #should this be "data4"?

for toppath in $PATH1 $PATH2 $PATH3 $PATH4; do
  for subdir in $(find $toppath -maxdepth 1 -name 'msg00[0-9]'); do
    /bin/echo -n "$subdir: "
    find $subdir -type f | wc -l
  done
done
