man tr, in particular the -s option

Also if you have a value in a variable, simply echoing it will normalize the spacing if you don't quote it (but this has other risks if the string value might contain special characters).

in Perl:
Code:
my $str = "ABC                           DEF";
$str =~ s/\s{2,}/ /g;    # substitute two or more spaces with a single one, globally

in vi mode

:%s/ / /g

essentially every 2 spaces in the file change to 1 space
