Hi Roger,

This has been discussed on this list earlier today, take a look at the
mail exchange with subject "jruby -e?"

Essentially, this is Windows limitation/feature. You should use double
quotes at the top level.

jruby -e "1000.times {}"

Thanks,

Hate to push back, but since it works with MRI I'd expect it to with
jruby.

Indeed, many people been bitten by this issue, and it is especially
confusing for newcomers to JRuby. When I first tried JRuby on windows
I also used  single quotes and thought for a while that the command
line in JRuby just plain totally broken, until switched to double
quotes.

Please, file a bug in http://jira.codehaus.org/browse/JRUBY

Thanks,

Thanks! I took a quick look at MRI's rb_win32_cmdvector(), which is
*250*(!) lines long, with two big loops, and it looks like MRI folks
do lots of extra magic with the command line parameters, including the
handling of single quote.

Thanks,
