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!

mkdtemp
MKDTEMP(3) Linux Programmer's Manual MKDTEMP(3)NAME
mkdtemp - create a unique temporary directory
SYNOPSIS
#include <stdlib.h>
char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
mkdtemp():
_BSD_SOURCE
|| /* Since glibc 2.10: */
(_POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700)
DESCRIPTION
The mkdtemp() function generates a uniquely named temporary directory from template. The last six characters of template must be XXXXXX
and these are replaced with a string that makes the directory name unique. The directory is then created with permissions 0700. Since it
will be modified, template must not be a string constant, but should be declared as a character array.
RETURN VALUE
The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appro-
priately.
ERRORS
EINVAL The last six characters of template were not XXXXXX. Now template is unchanged.
Also see mkdir(2) for other possible values for errno.
VERSIONS
Available since glibc 2.1.91.
CONFORMING TO
POSIX.1-2008. This function is present on the BSDs.
