Details:

We run these commands:
Here=/etc

find "$Here"            -perm /u=x,g=x,o=x   -type f                    
>/tmp/allbins

find "$Here"            -perm /u=x,g=x,o=x   -type f -ls                
>/tmp/allbins-ls

find "$Here"  -print0           -perm /u=x,g=x,o=x   -type f    >/tmp/allbins-z

wc -l /tmp/allbins

wc -l /tmp/allbins-ls

cat /tmp/allbins-z | tr '\0' '\n' | wc -l


The output is:

$ sudo bash t.sh
101 /tmp/allbins
101 /tmp/allbins-ls
3779

.... So it looks like there are 3779 files listed when we ask for -print0.
A quiick perusal using :  cat /tmp/allbins-z | tr '\0' '\n'   shows:

/etc
/etc/fstab
/etc/crypttab
/etc/mtab
/etc/resolv.conf
/etc/fonts
/etc/fonts/conf.d
/etc/fonts/conf.d/65-0-lohit-tamil.conf
/etc/fonts/conf.d/59-liberation-mono.conf
/etc/fonts/conf.d/66-ucs-miscfixed.conf
/etc/fonts/conf.d/59-liberation-sans.conf

.. all of which are not type f or mode executable


This sure looks like a bug!

Regards,


George
