[SOLVED] In bash, how to store top-level dirs in an array for post-processing?

Issue

I'm trying to get a list of my top-level dirs in a subdir, so I can post process them, e.g., delete certain ones. I have

# List the top-level dirs and create an array with the resul
DIRS=`ls -1`
IFS=$'\n' read -ra TOP_DIRS <<< "$DIRS"

# Iterate the array
for D in "${TOP_DIRS[@]}"; do
    # For now, just echo the dirs
    echo $D
done

The ls -1 command gives me this for example

00 PRM - AUTO GA
00 PRM - AUTO GA Prod
00 PRM - AUTO GA Prod@script
00 PRM - AUTO GA Prod@script@tmp
00 PRM - AUTO GA STG
00 PRM - AUTO GA STG@script
00 PRM - AUTO GA STG@script@tmp

However, the for loop only echoes the first value, that is

$ ./clean_workspace.sh 
00 PRM - AUTO GA

So obviously my IFS statement is wrong. What am I missing? TIA!

Solution

There's no need for ls. Just use a wildcard in an array literal.

top_dirs=(*)

BTW, it's bad style to use uppercase names for your variables. These are conventionally reserved for environment variables.
