My idea is to make a script which gives all subdirectories (in my case ˜/MUSIC but on the mac of my wife is it different –> artist/album).
In a later fase I would like convert all .wav extensions to mp4 (if not already exist).

But I have already troubles to get the output of the command in to a string array

```
#!/bin/bash

extFROM=”.wav”;
extTO=”.mp4”;

dir="˜/music";

tree -d

cnt=1;

array;

echo "  part 1";
find $dir -type d | while read line
#ls -d -1 | while read line
do
   array[ $cnt ] = "$line";
   echo "${cnt} "; # :  ${array[ $cnt ] ";
   let cnt++;
done

echo " part 2";
array=`awk '{print $1}' <find $dir -type d`
for i in array;
do
   echo "${i} ";
done

```

*My apologizes for the delay for my late reaction.
Part 1 and part 2 are having the same goal.*

Thanks **@Peter Cordes** for the information about to use 'while' instead 'for-loop' reading lines;
<http://mywiki.wooledge.org/BashFAQ/001> and <http://mywiki.wooledge.org/DontReadLinesWithFor>
And of course for your other reactions, it is great so many usefull input.

**@Matthew Bohnsack** … nice and easy piece of script, instead of my idea.

**@Saul Ortega**, this is my output : (of course the tree)

```
./test.sh: line 15: array: command not found
part 1
find: ˜/music: No such file or directory
part 2
./test.sh: line 28: find: No such file or directory
array 

```

So it has something to do with my script, the directory exist.
