your right:
/bin $ uname -a; ls -ld ls ls.exe

Not sure how a zero byte /bin/ls file was created. - my WAG: it was
the result of a "cut and paste" accident back on Dec 26 at the bash
commandline; or some other badly formed interactive bash commandline. My
bash PS1 env var ends with "> " - I'm going to fix that! If I had
pasted multiple lines from my window scroll history, the leading "> "
would have resulted in a zero byte file for each "arg 0" in the scroll
history - that had been mistakely pasted into a bash session.
The new snapshot is working fine now that the 0 byte /bin/ls file is gone:
~ $ date;uname -a; ls -l /etc/passwd

I've saved the strace test and output snippet for future reference. I'll
locate and fix all other bogus 0 byte files (if any), with:
find /usr -type f -empty |egrep -v '\.bs$'
Thanks for your patience, and follow through!
