keep command is ignoring my inputted filename and creating a file called keep. Running brlcad 7.16.1 rev36360 on OSX 10.5.8
This issue has been resolved in the latest (unreleased) version of the source code. Thank you for bringing the issue to our attention! You're welcome and encouraged to test and make sure this issue is resolved after the next source release of BRL-CAD.
This problem is fixed in r36464. Saving to a file named 'keep' was just lucky behavior. The problem was a bit more insidious in that the result was dependent upon previous actions taken, which could cause the keep command to use keep, some other file name, or even crash. The change snuck in and should be part of release 7.16.2
