Re:chmod without binary counting

Posted by: Administrator on February 01, 2004 12:47 AM

Actually, "a" is for "all" meaning all three levels (user, group, others). Here's an example:

<TT>r--r----- myfile.txt

chmod u+w myfile.txt
rw-r----- myfile.txt

chmod g+w myfile.txt
rw-rw---- myfile.txt

chmod o+r myfile.txt
rw-rw-r-- myfile.txt

chmod a+x myfile.txt
rwxrwxr-x myfile.txt</TT>

u = user
g = group
o = others
a = all

You can also combine the letters, like so:

<TT>chmod go-wx,u+w myfile.txt</TT>

you can also do this:

<TT>chmod u=rwx,g=rx,o=r myfile.txt</TT>

or this:

<TT>chmod ugo=rw myfile.txt</TT>

..and so on and so on.
