Unlike bash, ksh93 seems to do variable expansion before brace expansion. (Scrutinizer just said it.)

Master_Mind, I am not fully getting your requirement, but here is how you can adjust the ctry_input variable
Code:
#!/bin/sh
ctry_input=$1
case $ctry_input in
nz|usa|uk)
;;
*)
  ctry_input=aus
;;
esac
sed "s/@ctry/$ctry_input/"

This sample script you can run with a "uk" or "usa" argument, for example
Code:
sh sample.sh uk < inputfile

To meet your sourc/diff replacement requirement, you can move the sed into the case-branch:
Code:
#!/bin/sh
ctry_input=$1
case $ctry_input in
nz|usa|uk)
  sed "s/@ctry/$ctry_input/
  s/source_table/diff_table/"
;;
*)
  ctry_input=aus
  sed "s/@ctry/$ctry_input/"
;;
esac

NAME
replace - a string-replacement utility SYNOPSIS
replace arguments DESCRIPTION
The replace utility program changes strings in place in files or on the standard input. Note The replace utility is deprecated as of MySQL 5.7.18 and is removed in MySQL 8.0. Invoke replace in one of the following ways: shell> replace from to [from to] ... -- file_name [file_name] ... shell> replace from to [from to] ... < file_name from represents a string to look for and to represents its replacement. There can be one or more pairs of strings. Use the -- option to indicate where the string-replacement list ends and the file names begin. In this case, any file named on the command line is modified in place, so you may want to make a copy of the original before converting it. replace prints a message indicating which of the input files it actually modifies. If the -- option is not given, replace reads the standard input and writes to the standard output. replace uses a finite state machine to match longer strings first. It can be used to swap strings. For example, the following command swaps a and b in the given files, file1 and file2: shell> replace a b b a -- file1 file2 ... replace supports the following options. o -?, -I Display a help message and exit. o -#debug_options Enable debugging. o -s Silent mode. Print less information what the program does. o -v Verbose mode. Print more information about what the program does. o -V Display version information and exit. COPYRIGHT
