The last three letters in the permissions column tell us what everyone else in the world, the “others” may do.
-rwxr-x r-x joe acctg archive.sh -rw-rw- r-- joe acctg orgchart.gif -rw-rw- r-- joe acctg personnel.txt -rw-r-- r-- joe acctg publicity.html drwxrwx r-x joe acctg sales -rw-r-- --- joe acctg topsecret.inf -rwxr-x r-x joe acctg wordmatic
The “others” lead highly restricted lives.
They can’t write any files or directories, and they have absolutely
no access to the topsecret.inf
file.
They may still run the archive.sh
script and
the wordmatic
program, and they may search
the sales
directory.
However, things are not as we should like.
archive.sh
(although they can read it to learn how to write a good shell script).
topsecret.inf
so that it’s closed off
to everyone except user Joe.
sales
directory to
outsiders.
publicity.html
file contains
press releases, and it should be open to anyone in the company to
change.
