NOTE: Only tested in (Arch) GNU/Linux.
Description
-
backup.sh: Copies files and folders of interest to a specified location by a
.conf
file. This configuration file looks like:/home/user/directory_A /home/user/directory_B /home/user/directory_C /home/user/file_A.sh /home/user/file_B.rs /home/user/file_C.so
There can be different profiles, each with its own
.conf
and destination. By default, I added HOME and WORK. Simple. But you can add as many as you like. To backup the data, typebackup home
orbackup work
in a terminal. -
nvidia.sh: Enables or disables discrete NVIDIA (OPTIMUS) GPU. Useful to extend battery life in beefy laptops when this GPU is not needed. Type
nvidia on
ornvidia off
. NOTE: will ask for administrator (root) password to change status of/proc/acpi/bbswitch
. -
wifi.sh: Enables or disables wireless interface (handy in non-distracting environments such as sway, herbstluftwm, i3, etc.). Type
wifi on
orwifi off
in a terminal. -
smt.sh: Enables or disables simultaneous multithreading (a.k.a. hyperthreading). Why would you...? If you crush numbers heavily (model data fitting, solving ODEs, etc) hyperthreading reduces the computer's performance by a factor of 2 (the program takes twice as long to complete). This is bad. However, it does improve performance in other tasks (i.e. compiling kernel takes half the time with hyperthreading). This is good. Type
hyperthreading on
orhyperthreading off
before running your software. NOTE: will ask for administrator (root) password to change status of/sys/devices/system/cpu/smt/control
. -
man.sh: Changes the default colours of the system reference manuals (
man
). Why not.
