#!/usr/bin/perl
$replace=pop;
$find=pop;
{local $^I=".bak"; local @ARGV=qw(file.txt);
 while( <> ){
    s/$find \S+/$find $replace/g;
     print;

Unless you meant to call
/perl script.pl file.txt cool! great!
in which case you might use
 #!/usr/bin/perl
$replace=pop;
$find=pop;
{local $^I=".bak";
 while( <> ){
    s/\b$find\b/$replace/g;
     print;
 }
}

When the first is called as
perl script.pl expert-exchange.com great!
It replaces the word after "expert-exchange.com" with "great!" in file.txt

when the second is called as
perl script.pl file,txt cool! great!
it replaces the word "cool!" with "great!" in "file.txt"
 
Is either of those close to what you wanted?
