Steam compatdata list

 I wrote a bash script for cleaning up compatdata and shadercache files for Steam games. I made it for myself and I'm only posting it here to find it later, but feel free to try/modify it yourself, if you like. Just don't blame me if it all backfires.

 function steam_create_id_list()
{
    IFS=$'\n'
    echo "Input full path to steamapps folder:"
    read pathto
    compat_path="$pathto/compatdata/"
    shader_path="$pathto/shadercache/"
    nn=${#compat_path}
    nn=$(( nn + 1 ))
    results_names=()
    results_id=()
    array=($(ls -d $compat_path/*))
    echo "" > "results.txt"
    for i in "${array[@]}";do
        echo $i
        ID=$(echo ${i##*/})
        echo $ID
        ID=''$ID''
        steam_api_call $ID
        if [[ $NAME == "" ]];then
            continue
        fi
        if [[ $NAME == "null" ]];then
            continue
        fi
        results_names+=($NAME)
        results_id+=($ID)
        echo "$ID is $NAME"
    done
    echo $results
}

function steam_api_call()
{
    URL="https://store.steampowered.com/api/appdetails?appids=$1";CALL="$(curl -s GET $URL)";NAME="$(echo $CALL | jq -r '.["'$1'"]["data"]["name"]')"
}

function create_list()
{
    count=0
    for i in "${results_names[@]}";do
        echo "$count)    $i"
        count=$(( count + 1 ))
    done
}

function dir_test_delete()
{
    if [ -d "$1" ]; then
        echo "deleting $1"
        rm -r "$1"
    fi
}

function choice_hang()
{
    prompt="Select prefix to clear (or exit/list):"
    echo $prompt
    read choice
    if [[ $choice == "exit" ]];then
        exit
    fi
    if [[ $choice == "list" ]];then
        create_list
        echo "List WILL NOT update until restart"
        echo $prompt
    fi
    if [[ $choice =~ [a-zA-Z] ]]; then
        echo "numbers only"
    fi
    if [[ $choice =~ [0-9] ]]; then
        echo "Really delete ${results_id[$choice]} (${results_names[$choice]})? <y/n>"
        read choiceb
        if [[ $choiceb == "y" ]];then
            dir_to_delete_comp="$compat_path/${results_id[$choice]}"
            dir_to_delete_shad="$shader_path/${results_id[$choice]}"
            dir_test_delete $dir_to_delete_comp
            dir_test_delete $dir_to_delete_shad
        fi
    fi
}
