#!/bin/bash
declare -a dirs
index=0
for dir in `ls -d */`
do
dirs[$index]=$dir
echo $index. $dir
index=`expr $index + 1`
done

Its giving me distorted output:

c.sh: dirs[0]=1/: No such file or directory
0. 1/
c.sh: dirs[1]=11844/: No such file or directory

  1. 11844/
    c.sh: dirs[2]=12819/: No such file or directory
  2. 12819/
    c.sh: dirs[3]=15734/: No such file or directory
  3. 15734/
    c.sh: dirs[4]=16217/: No such file or directory
  4. 16217/

How can I fix this

That is because of you have higher (2.5) version of bash. My issues is that I need to display list of directories under a path and then take the user input to navigate so I need an array else it would become difficult.

Not sure what other solution I can avail
