The question does not have to be directly related to Linux and any language is fair game.

Hi all, my name is Rick. I’m using red hat 9.0
Can somebody show me how to add many accounts by a bash script?
I need to perform the following functions:
1) I have a file called userfile.txt. It contains new users’ information. The format is like this:
so on ...
2) I now need to create a shell script called:myscript , this script program will read the userfile.txt file and process the user account.
1.To use this program, user must type this command: “myscript userfile.txt”. If user does not type in this way, system will display the error message—“you type in wrong way !”
2.If people type in myscript –h, system will display some information to the users.
Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
use the adduser with --stdin option to create a count with an uncrypted passwd.
after that you have to crypt the passwd. this a small program in C to crypt a passwd:
char *crypt(const char *key, const char *salt);
//char *crypt(char *key, char *salt);
char key="mt"; // some couple of characters see man crypt
crypted = new char ;
printf ("\n enter password ");
crypted = crypt( passwd, key);
printf ("\nthe passwd before is %s after is %s ", passwd, crypted);
to compile it, add the crypt library
g++ crypt1.c -lcrypt
