Bash Script to Ash (busybox) - Beginner

Hi All,

I have a script that I wrote on a bash shell, I use it to sort files from a directory into various other directories. I have an variable set, which is an array of strings, I then check each file against the array and if it is in there the script sorts it into the correct folder.

But now I need to move this script to ash, the only part of the script that is giving my bother is the array part, as the other commands are fairly basic commands, if, mv, etc.

I've been searching around but haven't found what I am looking for. Would anyone have any Ideas on how to replace the array in my bash script.

I have an example of what I am doing, obviously in the full script the array is much longer, and there is no point in putting in what I am doing with the files as thats all good.

Essentially, I have the array set, I read the list of files then and using a while loop, I call the sortmove function with then searches the array.

Code:

DESTDIR="/destination/"
SORTDIR="/source/"
STRINGS=(
		"string1"
		"string2"
		"string3"
		)



sortmove ()
{
	found=0
	for (( i=0; i<${#STRINGS[@]}; i++ ))
	do
	if [ "${STRINGS[$i]}" == "$3" ];
	then
		do something
	fi
	done
}

ls "${SORTDIR%%/}"/*.mp4 | while read filename
	do
		some processing
		
		sortmove var1 var2 var3
	
	done

SCRIPT(1)						    BSD General Commands Manual 						 SCRIPT(1)

NAME

     script -- make typescript of terminal session

SYNOPSIS

     script [-a] [-f] [-q] [-t] [file]

DESCRIPTION

     Script makes a typescript of everything printed on your terminal.	It is useful for students who need a hardcopy record of an interactive
     session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.	If no file name is given, the typescript is saved in the file typescript.

     Options:

     -a      Append the output to file or typescript, retaining the prior contents.

     -f      Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
	     vise real-time what is being done using `cat foo'.

     -q      Be quiet.

     -t      Output timeing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
	     elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
	     to replay typescripts with realistic typing and output delays.

     The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
     set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the typescript file.  Script works best with commands that do not manipulate
     the screen, the results are meant to emulate a hardcopy terminal.

ENVIRONMENT

     The following environment variable is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
	    shells set this variable automatically).

SEE ALSO

     csh(1) (for the history mechanism), replay(1).

HISTORY

     The script command appeared in 3.0BSD.

BUGS

     Script places everything in the log file, including linefeeds and backspaces.  This is not what the naive user expects.
