That's distressing. It looks like there is something wrong with your /bin/mv. The fact that it's referring to line numbers makes it look like it thinks it's a text file, like a shell script, which it shouldn't be, but then the strings like __PAGEZERO and __TEXT that it's encountering within the file look like normal parts of a Mach-O executable.

Let's see if we can learn more about your /bin/mv... What's the output of:

file /bin/mv
ls -l /bin/mv
/bin/mv

What OS version is this? On OS X 10.11 and later, System Integrity Protection should have prevented any unwanted modifications of system files like /bin/mv, unless you've turned SIP off.
