Hi.
What the others have said is correct: a hyphen indicates that permission
is disabled. This means that you permission string above '-rwxr-xr-x'
unpacks as
- rwx r-x r-x
with the groups for directory, owner, group, world in that order:
directory - (is not a directory)
owner rwx (read, write, execute)
group r-x (read, execute)
world r-x (read, execute)
note that each value is a bit, and three bit groups allows the
complete set to be represented conveniently in octal. In this
case 755. Remember that value - you'll see it a lot!
HTH,
