I apologize for this beforehand, but maybe there's a simple answer.  I'm very new to uboot.

I've gotten myself into a tough spot.  There's a application on my computer preventing my boot from completing, since it freezes.  I can fix it if I can just remove/corrupt the guilty file on my file system.  So I stop the boot and enter into the uboot command line.  I can see the file I want to remove, but I am not skilled enough to know if/how I can alter it or remove it from the uboot command line.  I'm using version 1.1.3.

If such a thing is possible I would appreciate instructions.

Thanks.
