I am writing my first shell script to do the following:
Find all occurrences of a directory from the pwd
Delete the directory (which is a hidden directory)
Provide feedback w/ the number of directories deleted
The problems I am having are two-fold:
The user may not have the appropriate privileges to delete the directory
grep -c counts the total number of lines returned, rather than the total number of unique occurrences of the directory
For example, I want to let the user know how my directories called "delete_me" were deleted. If the directory structure is /.delete_me/subdir1/subdir2, grep -c returns "3" (/.delete_me, /.delete_me/subdir1, and /.delete_me/subdir1/subdir2). I want to tell the user that 1 directory called ".delete_me" was deleted. How can this be done?
My other problem deals w/ the user not having privileges to delete the directory, or getting feedback on all the directories accessed during the "find" that they don't have permission to read. Ideally, the script would be run w/ root privileges, but I can only get it to run w/ the privileges assigned to the user running the script.
A copy of my code is below. I am just testing, so right now I am not deleting any directories, just finding them and printing to stdout.
Any help would be greatly appreciated. Thanks in advance.

misc_conv
MISC_CONV(3) Linux-PAM Manual MISC_CONV(3)NAME
misc_conv - text based conversation function
SYNOPSIS
#include <security/pam_misc.h>
int misc_conv(int num_msg, const struct pam_message **msgm, struct pam_response **response, void *appdata_ptr);
DESCRIPTION
The misc_conv function is part of libpam_misc and not of the standard libpam library. This function will prompt the user with the
appropriate comments and obtain the appropriate inputs as directed by authentication modules.
In addition to simply slotting into the appropriate pam_conv(3), this function provides some time-out facilities. The function exports five
variables that can be used by an application programmer to limit the amount of time this conversation function will spend waiting for the
user to type something. The five variabls are as follows:
time_t pam_misc_conv_warn_time;
This variable contains the time (as returned by time(2)) that the user should be first warned that the clock is ticking. By default it
has the value 0, which indicates that no such warning will be given. The application may set its value to sometime in the future, but
this should be done prior to passing control to the Linux-PAM library.
const char *pam_misc_conv_warn_line;
Used in conjuction with pam_misc_conv_warn_time, this variable is a pointer to the string that will be displayed when it becomes time
to warn the user that the timeout is approaching. Its default value is a translated version of "...Time is running out...", but this
can be changed by the application prior to passing control to Linux-PAM.
time_t pam_misc_conv_die_time;
This variable contains the time (as returned by time(2)) that the will time out. By default it has the value 0, which indicates that
the conversation function will not timeout. The application may set its value to sometime in the future, but this should be done prior
to passing control to the Linux-PAM library.
const char *pam_misc_conv_die_line;
Used in conjuction with pam_misc_conv_die_time, this variable is a pointer to the string that will be displayed when the conversation
times out. Its default value is a translated version of "...Sorry, your time is up!", but this can be changed by the application prior
to passing control to Linux-PAM.
int pam_misc_conv_died;
Following a return from the Linux-PAM libraray, the value of this variable indicates whether the conversation has timed out. A value of
1 indicates the time-out occurred.
The following two function pointers are available for supporting binary prompts in the conversation function. They are optimized for the
current incarnation of the libpamc library and are subject to change.
int (*pam_binary_handler_fn)(void *appdata, pamc_bp_t *prompt_p);
This function pointer is initialized to NULL but can be filled with a function that provides machine-machine (hidden) message exchange.
It is intended for use with hidden authentication protocols such as RSA or Diffie-Hellman key exchanges. (This is still under
development.)
int (*pam_binary_handler_free)(void *appdata, pamc_bp_t *delete_me);
This function pointer is initialized to PAM_BP_RENEW(delete_me, 0, 0), but can be redefined as desired by the application.
SEE ALSO pam_conv(3), pam(8)STANDARDS
The misc_conv function is part of the libpam_misc Library and not defined in any standard.
