What's the difference between chmod 0755 file and chmod 755 file?

I found this - http://en.wikipedia.org/wiki/Chmod#Special_modes -, hope this is it.

None, since the octal numbers are read from right to left.

There is no difference between 0755 and 755 because by default 755 starts with a zero....

But yes there is a difference between 0755 and 1755.. in later sticky bit is switched on that allow only owner of the resource to delete it...

Hope this helps

This is the difference...

Code:

0755  --- None of the special bits set
1755  --- Sticky bit set
2755  --- SGID bit set
4755  --- SUID bit set

Google for sticky,SGID and SUID bits.

Yes, but there is no difference between 755 and 0755, regardless of the status of the special bits.

If you read the reference by rfernandez you'll see that it makes explicit that 0755 specifies the state of the special bits, where 755 doesn't. Obvious really...
