Welcome to KDUSM information page.
KDUSM is a script that works with some commands that help to manage kernels, drivers and users.

ATTENTION
*The number 3, 4, 5, 7 and 8 can break your system. WARNING! USE WITH CAUTION.

e - EXIT KDUSM
"clear && exit"
This will exit KDUSM.

i - INFORMATION KDUSM
Display this information page.

1 - LIST AVAILABLE MANJARO KERNELS
Will be listed all the Manjaro kernels.
"mhwd-kernel -l"

2 - LIST INSTALLED KERNELS
Will be listed all kernels installed on your system.
"mhwd-kernel -li" 

3 - INSTALL A KERNEL
Install new kernel(s): Add a valid linux kernel number directly after linux (no space) to the following command, where you can also choose to add (as shown in the following example)
multiple kernels (always separated by a space).
"sudo mhwd-kernel -i linux linux313 linux312"

4 - REMOVE A KERNEL
Remove one or more installed kernels: (leave at  least one!). The following example has both the 34 & 311 kernels included.
"sudo mhwd-kernel -r linux34 linux311"

5 - REMOVE A KERNEL/INSTALL OTHER
Remove currently running kernel & install those specified.
"sudo mhwd-kernel <add kernel(s) here> rmc" 
NOTE: the rmc option is essential to this command.

6- WIKI MHWD-KERNEL
Visit the Manjaro Linux wiki about mhwd-kernel.

7 - USE FREE DRIVERS
Install either free drivers (e.g. provided by the Linux community).
"mhwd -a pci free 0300"
 
8 - USE NOFREE DRIVERS
Install nonfree drivers (e.g. provided by hardware manufacturers).
"mhwd -a pci nonfree 0300"

9 - LIST INSTALL DRIVERS
A more detailed list of installed drivers.
"mhwd -l -d"
 
10 - LIST INSTALL DRIVERS PCI
using the --pci filter in the following example will list detailed information for only the drivers available for devices (e.g. graphics cards) using an internal PCI connection.
"mhwd -l -d --pci"

11- WIKI MHWD-DRIVERS
Visit the Manjaro Linux wiki about mhwd-driver.

12 - SHOW ALL USERS
Displays all users on your system.
"cut -d: -f1 /etc/passwd"

13 - ADDING A USER
Adding a new user to your system.
"useradd <name.of.user>"

14 - DELETING A USER
Removing a user from your system.
"userDEL <name.of.user>"

15- WIKI USERS-GROUPS
Visit the Manjaro Linux wiki about users and groups.
