I am new to using unix and am struggling with a script i am writing. What i am trying to do is get a user to enter a username, check the original file i created with username and pin to see if their is a corresponding entry. Next ask the user to enter the pin and see if this matches corresponding username. Is it possible to do this by using a cat and grep command or is there another way. You can see the progress I have made below. Any help would be massively appreciated.
Thanks
Code:
while :
do
echo "enter a name"
read user
cut -f1 usernames | grep -i -q "$user"
a=$?
echo "enter a password"
read pass
cut -f2 usernames | grep -q "$pass"
b=$?
if [ $a = 0 ] && [ $b = 0 ]
then
echo "welcome"
menu
exit
else
echo "access denied please try again"
fi
done
The only problem with this is that the password grep does not search for the corresponding username.
Is the following even possible ? by echo $3, I mean enter password when prompted for it. My main issue is that it would deal with a prompted password, which is passed from the command line like this:
./processing serverA user password

ne_forget_auth
NE_SET_SERVER_AUTH(3) neon API reference NE_SET_SERVER_AUTH(3)NAME
ne_set_server_auth, ne_set_proxy_auth, ne_forget_auth - register authentication callbacks
SYNOPSIS
#include <ne_auth.h>
typedef int (*ne_auth_creds)(void *userdata, const char *realm, int attempt, char *username, char *password);
void ne_set_server_auth(ne_session *session, ne_auth_creds callback, void *userdata);
void ne_set_proxy_auth(ne_session *session, ne_auth_creds callback, void *userdata);
void ne_forget_auth(ne_session *session);
DESCRIPTION
The ne_auth_creds function type defines a callback which is invoked when a server or proxy server requires user authentication for a
particular request. The realm string is supplied by the server. The attempt is a counter giving the number of times the request has been
retried with different authentication credentials. The first time the callback is invoked for a particular request, attempt will be zero.
To retry the request using new authentication credentials, the callback should return zero, and the username and password buffers must
contain NUL-terminated strings. The NE_ABUFSIZ constant gives the size of these buffers.
Tip
If you only wish to allow the user one attempt to enter credentials, use the value of the attempt parameter as the return value of the
callback.
To abort the request, the callback should return a non-zero value; in which case the contents of the username and password buffers are
ignored.
The ne_forget_auth function can be used to discard the cached authentication credentials.
EXAMPLES
/* Function which prompts for a line of user input: */
extern char *prompt_for(const char *prompt);
static int
my_auth(void *userdata, const char *realm, int attempts,
char *username, char *password)
{
strncpy(username, prompt_for("Username: "), NE_ABUFSIZ);
strncpy(password, prompt_for("Password: "), NE_ABUFSIZ);
return attempts;
}
int main(...)
{
ne_session *sess = ne_session_create(...);
ne_set_server_auth(sess, my_auth, NULL);
/* ... */
