[Rails] Re: executing an external application within rails

[Jonathan Conway]

Thank I've got a little bit further. It now works for date using the 
full path /bin/date but if say do something like %x{/usr/local/bin/svn} 
(this is just a test example), I thought I should at least get the svn 
message asking me for the parameters, but instead I get nothing back. 
Very strange.

It works without problem from /script/console and irb.. just not withing 
a rails app.

Any help greatly appreciated

Jon
