+As discussed on the BashNotes page, scripts can cope with arguments that contain spaces if you are careful. <tt>bash</tt> will expand *$@* as all of its arguments, but importantly will expand *"$@"* as each argument surrounded by "quote marks". Eg, if a script is called with arguments
+<verbatim>
+ ./myscript "argument 1" "argument 2"
+</verbatim>
+then a script that did
+<verbatim>
+ perl -e 'foreach $a (@ARGV) {print ".$a.\n"}' $@
+</verbatim>
+would output
+<verbatim>
+.argument.
+.1.
+.argument.
+.2.
+</verbatim>
+while a script that did
+<verbatim>
+ perl -e 'foreach $a (@ARGV) {print ".$a.\n"}' "$@"
+</verbatim>
+would output
+<verbatim>
+.argument 1.
+.argument 2.
+</verbatim>
