Just wondering, what's chmod a+w is numeric terms? 666?

Thanks,

I believe it gives the admin group write access to the file you are chmoding.

Therefor, it just adds writing capablities for the first number if you will. You can really tell what the numeric term is because it could be a combination of permissions such as read+write, or execute+write, etc.

Hmm thanks, though do you know the exact numeric equivilant if I try and do this using FTP? I don't want to get it wrong, since it could be a security hazzard.

Actually the "a" is for "all". So it gives everyone (user, group, others) write access to the file. The numeric value for this (which would mean no-one could read the file, only write, so it's not that useful) would be 222.

However, remember "a+w" adds the permissions to the existing permissions.

Thanks Phil!

Oops. Im still learning. :)

+r = read +x execute

r = read
w = write
u = permissions for file owner
g = permissions for file group
t = sticky bit
x = execute or access
s = suid

probably forgot one or two
