That is another neat way of doing it, unfortunately
when I run it twice, it doesn't give out the output that the user or uid exist
Also, when I ssh to remote server, the home directory hasn't been created by script

Thanks Guys for the -p option in useradd.
The password side of my script is now working
However, it doesn't create home directory using the script and also the if arguments kept re-create user instead of saying "User ID does exist....." if I ran the script twice
Can someone have another second look please?

I have a directory full of zip files.
How would I write a bash script to enumerate all the zip files, remove the ".zip" from the file name, create a directory by that name and unzip each zip file into its corresponding directory?
Thanks!

useradd(8) System Manager's Manual useradd(8)NAME
useradd - create a new user account
SYNOPSIS
useradd [-D binddn] [-P path] [-c comment] [-d homedir]
[-e expire] [-f inactive] [-G group,...] [-g gid]
[-m [-k skeldir]] [-o] [-p password] [-u uid]
[-U umask] [-r] [-s shell] [--service service] [--help]
[--usage] [-v] [--preferred-uid uid] account
useradd --show-defaults
useradd --save-defaults [-d homedir] [-e expire] [-f inactive]
[-g gid] [-G group,...] [-k skeldir] [-U umask] [-s shell]
DESCRIPTION
useradd creates a new user account using the default values from /etc/default/useradd and the specified on the command line. Depending on
the command line options the new account will be added to the system files or LDAP database, the home directory will be created and the
initial default files and directories will be copied.
The account name must begin with an alphabetic character and the rest of the string should be from the POSIX portable character class ([A-
Za-z_][A-Za-z0-9_-.]*[A-Za-z0-9_-.$]).
OPTIONS -c, --comment comment
This option specifies the users finger information.
-d, --home homedir
This option specifies the users home directory. If not specified, the default from /etc/default/useradd is used.
-e, --expire expire
With this option the date when the account will be expired can be changed. expiredate has to be specified as number of days since
January 1st, 1970. The date may also be expressed in the format YYYY-MM-DD. If not specified, the default from /etc/default/useradd
is used.
-f, --inactive inactive
This option is used to set the number of days of inactivity after a password has expired before the account is locked. A user whose
account is locked must contact the system administrator before being able to use the account again. A value of -1 disables this
feature. If not specified, the default from /etc/default/useradd is used.
-G, --groups group,...
With this option a list of supplementary groups can be specified, which the user should become a member of. Each group is separated
from the next one only by a comma, without whitespace. If not specified, the default from /etc/default/useradd is used.
-g, --gid gid
The group name or number of the user's main group. The group name or number must refer to an already existing group. If not speci-
fied, the default from /etc/default/useradd is used.
-k, --skel skeldir
Specify an alternative skel directory. This option is only valid, if the home directory for the new user should be created, too. If
not specified, the default from /etc/default/useradd or /etc/skel is used.
-m, --create-home
Create home directory for new user account.
-o, --non-unique
Allow duplicate (non-unique) User IDs.
-p, --password password
Encrypted password as returned by crypt(3) for the new account. The default is to disable the account.
-U, --umask umask
The permission mask is initialized to this value. It is used by useradd for creating new home directories. The default is taken from
/etc/default/useradd.
-u, --uid uid
Force the new userid to be the given number. This value must be positive and unique. The default is to use the first free ID after
the greatest used one. The range from which the user ID is chosen can be specified in /etc/login.defs.
--preferred-uid uid
Set the new userid to the specified value if possible. If that value is already in use the first free ID will be chosen as described
above.
-r, --system
Create a system account. A system account is an user with an UID between SYSTEM_UID_MIN and SYSTEM_UID_MAX as defined in
/etc/login.defs, if no UID is specified. The GROUPS entry in /etc/default/useradd is ignored, too.
-s, --shell shell
Specify user's login shell. The default for normal user accounts is taken from /etc/default/useradd, the default for system accounts
is /bin/false.
--service service
Add the account to a special directory. The default is files, but ldap is also valid.
-D, --binddn binddn
Use the Distinguished Name binddn to bind to the LDAP directory. The user will be prompted for a password for simple authentica-
tion.
-P, --path path

/etc/shadow.
