Something that isn't mentioned in the Ruby manual online (http:// www.rubycentral.com/book/ref_m_kernel.html#Kernel.system) is that the entire path is needed as well. Of course, that is a best practice, but I spent some time working through this as an issue. Additionally, I wrote a short test.sh script that does an exit with a value. The command I used in ruby was: retval = system("/path/to/test.sh") when this is run the values for 'retval' and $? are as follows: #exit 0 -> true $?=0 #exit 1 -> false $?=256 #exit 2 -> false $?=512 #exit 3 -> false $?=768 #exit 4 -> false $?=1024 #exit 5 -> false $?=1280 #exit -1 -> false $?=65280 Can anyone explain the $? values? It is supposed to contain a 'detailed error code'. By the looks of it, some sort of multiple of 256. Mike B.
