With any POSIX conforming shell, there is no need for awk, cut, expr, or any other substring operation:
Code:
#!/bin/ksh
IAm=${0##*/}
case "$1" in
(B*)	DIR=/database/banking;;
(M*)	DIR=/database/manufacturer;;
(R*)	DIR=/database/retailer;;
(*)	printf '%s: database should start with "B", "M", or "R"\n' "$IAm" >&2
	printf 'Usage: %s database\n' "$IAm" >&2
	exit 1;;
esac
printf 'Using DIR="%s" for database="%s"\n' "$DIR" "$1"

apple_dump

APPLE_DUMP(1)                                                      Netatalk 2.2                                                      APPLE_DUMP(1)

NAME

       apple_dump - Dump AppleSingle/AppleDouble format file

SYNOPSIS

       apple_dump [-a] FILE | DIR
                                                          apple_dump -f FILE
                                                          apple_dump -d FILE
                                                          apple_dump -h | -help | --help
                                                          apple_dump -v | -version | --version

DESCRIPTION

       apple_dump dump AppleSingle/AppleDouble format file.

OPTIONS

       -a FILE|DIR
           This is default. Dump a AppleSingle/AppleDouble file for FILE or DIR automatically. Extrapolate FinderInfo type from absolute path. If
           FILE is not AppleSingle/AppleDouble format, look for .AppleDouble/FILE and ._FILE. If DIR, look for DIR/.AppleDouble/.Parent and ._DIR.

       -f FILE
           Dump FILE. Assume FinderInfo to be FileInfo.

       -d FILE
           Dump FILE. Assume FinderInfo to be DirInfo.

       -h, -help, --help
           Display the help and exit

       -v, -version, --version
           Show version and exit

NOTE

       There is no way to detect whether FinderInfo is FileInfo or DirInfo. By default, apple_dump examins whether file or directory, a parent
       directory is .AppleDouble, filename is ._*, filename is .Parent, and so on.

       If setting option -f or -d, assume FinderInfo and doesn't look for another file.
