If an executable script called "myscript" was invoked from the command line as
we can save the parameters into named environment variables called say filename from $1 and the permissions parameter (755) from $2.
If we want to find out the current directory listing for the file myfile we can extend the script by one line. Any line starting with a hash character (#) a comment line and will be ignored by the shell.
Now we understand script parameters, we can take the saved $2 (now called ${perms} ) and substitute it into a unix chmod command.
Your turn!

console.perms
console.perms(5) System Administrator's Manual console.perms(5)NAME
console.perms - permissions control file for users at the system console
DESCRIPTION
/etc/security/console.perms and .perms files in the /etc/security/console.perms.d directory determine the permissions that will be given to
priviledged users of the console at login time, and the permissions to which to revert when the users log out. They are read by the
pam_console_apply helper executable.
The format is:
<class>=space-separated list of words
login-regexp|<login-class> perm dev-glob|<dev-class>
revert-mode revert-owner[.revert-group]
The revert-mode, revert-owner, and revert-group fields are optional, and default to 0600, root, and root, respectively.
The words in a class definition are evaluated as globs if they refer to files, but as regular expressions if they apply to a console defi-
nition. Do not mix them.
Any line can be broken and continued on the next line by using a character as the last character on the line.
The login-class class and the login-regexp word are evaluated as regular expressions. The dev-class and the dev-glob word are evaluated as
shell-style globs. If a name given corresponds to a directory, and if it is a mount point listed in /etc/fstab, the device node associated
with the filesystem mounted at that point will be substituted in its place.
Classes are denoted by being contained in < angle bracket > characters; a lack of < angle brackets > indicates that the string is to be
taken literally as a login-regexp or a dev-glob, depending on its input position.
