A script to get a random file

**Dear developers,** I have an issue with my script switching from Android 9 to 10 (devices from a Umidigi S3 Pro to a Umidigi F2). I have installed Bosybox App on the first and Busybox Magisk module on the latter. Now the script does not work because the command: list=(busybox find "$dirs" -type f -name *.$ext) returns an empty array. This is the complete script: #!/system/bin/sh echo if test "$1" = ""; then echo "Randomfile script by Uranya v1.4 01.01.2021" echo "Usage:" echo "sh randomfile.sh " exit 1 fi dirs=$1 ext=$2 dird=$3'/' dest=$dird'random' delim1="" delim2="" last='last.txt' # create filename's array IFS=$'\n' list=(busybox find "$dirs" -type f -name *.$ext) # count number of files num=${#list[@]} # generate random number in range 1-NUM let "ran=(${RANDOM} % ${num})+ 1" echo Random from $num files is $ran sour=${list[ran]} sourn=${sour#$dirs} sourn=${sourn:1:${#sourn}} date=$(date +"%Y.%m.%d %H:%M") day=$(date +"%d") hour=$(date +"%H") minute=$(date +"%M") message='---------------------------------------\n'$date' - '$num' >>> '$ran'\n'$delim1$sourn$delim2 if ([ "$day" = "01" ] && [[ "$minute" $dird$last $message else sed -i '1i'$message $dird$last fi echo $delim1$sourn$delim2 # rename the old file cp $dest.$ext $dest'_back.'$ext # copy the file cat "$sour" >$dest.$ext echo File copied as $delim1$dest.$ext$delim2 Can you please help me to understand why this happens, and how to fix it? Thank you very much for your attention!
