Linux has much more powerful scripting languages. A simple replacement would
be writing a "shell" script; "man bash" for more details.
You may be better served, however, with a something like perl, which is an
extremely powerful scripting language.
In perl, your script would probably look something like this (quick hack, not
verified, etc):
#! /usr/bin/env perl
use strict;
use warnings;
$|=1;
while( 1 )
{
print " Backup Menu";
print " ===========";
.....
print " Q. Quit";
print "Enter your choice: ";
<>; chomp;
if ( /a/ )
{
# Do something here...
}
elsif ( /b/ )
{
# Handle b here...
}
}
Hope this helps. Google for perl; there are a lot of perl resources out
there.
