    Hi all,

    How difficult is it to get this pseudo code to work under SHELL? This is the task I do every day. I m not sure how to start it. can anyone help?

    useradd username
    usermod -g username username
    passwd username
    vi /etc/passwd
    define home dir
    cd ~username
    remove all data
    then go to /home/usrbak
    cp username.tar.gz to /tmp
    cd tmp
    gzip -d username.tar.gz
    tar -xf username.tar
    mv * ~username
    vi /usr/local/apache/conf/include-conf/vhosts
    add the domain within the vhost
    cd ~username
    chown -R username:username .
    chmod -R 755 .
    service httpd restart

    Any assistance would be helpful. Thanks in adv.

    You could write a little script for it.

    Most of what you are doing can be done with useradd itself. Read the man page.

    The (moderately) tricky part is encrypting the password. I use a compiled C program as a front end to crypt(3):

    /********************************
    NAME: crypt.c
    AUTHOR: Chris F.A. Johnson
    DATE: 2003-01-23
    ********************************/
    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>
    #include <unistd.h>

    int
    main(int argc, char *argv[])
    {
    char *passwd;
    char buf[1024];
    char *salt;

    if (argc > 1)
    {
    salt = argv[1];
    puts(salt);
    }
    else
    {
    /* salt = "$1$!@#$%^&*"; */
    salt = NULL;
    }

    fgets(buf,sizeof(buf),stdin);
    if ( buf[strlen(buf)-1] == '\n' )
    {
    buf[strlen(buf) - 1] = '\0';
    }
    printf( "%s\n", encrypt(buf, salt));

    return 0;
    }
    /********************************/

    Do not use vi in a script. Describe what you want to do, and script it directly.

    Well, I think it's not that hard to make a bash script that does this...
