chmod 600 means rw-------. Which means the owner (root, in this case),
has read and write permissions, and group and others have none.
If you really used 600, even root should not be able to execute this
script. Try 'man chmod'. If you really want to save yourself confusion,
and don't know octal notation, use the letter designations.
a short description:
chmod u+[r][w][x] <file> gives the owner of the file read, write
and/or execute permission on file.
Note: you can give more than one of r/w/x
on the line at a time. For example, the
the following gives read and execute
permissions to the owner of the file named
"foo".
chmod u+rx foo
to set the group serttings for a file, change the "u" in the above
example to "g". For "others" (those not covered by group and user)
use "o" instead of "u". You can also use "a", for "all".
Also, change the "+" to a "-" to remove permissions.
Note that if you use "chmod a-x foo" on a file with permissions
rwxrwxrwx, you will get rw-rw-rw-. In other words, if you don't
specificly alter a type of permission on a filem like r or w, it
will not b altered.
