IIT:

Does it have multiple threads though?

Imagine fucking this up

How can I make this script not break after running it for the second time?
If I run it the second time it breaks when scanning for wireless networks and outputs "No networks found".

echo running "ip link set wlp9s0 down"
sudo ip link set wlp9s0 down
echo waiting for device to be sure of its active state
sleep 5
echo running wifi-menu
sudo wifi-menu

Trying to run wifi-menu manually after that script has run once also outputs "No networks found".

history -c

This thread is for useful scripts
Also I have no idea what wifi-menu is, I use wpa_supplicant

The script is useful the first time it's run.

simple script to let you control the CPU speed from cli

I wrote it so tell me any criticism. I like it because sometimes on de's they don't have a good gui option for cpu speed so I like to be able to manually set it. it's been useful when i'm helping a friend with their computer and getting it to speed up is needed .

Please star my repo if you use and like my code, or comment how I can improve. I take each star seriously.

#bash script that sets cpu settings

function main_menu

{

clear

cursetting=$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor)

getspd=$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq)

curspd=$(echo $getspd 1000000 | awk '{printf $1 / $2}')

echo "CPU freq"

echo "1. CPU min"

echo "2. CPU medium"

echo "3. CPU max"

echo "4. Now with exit commands!"

echo "Current CPU "$cursetting;

echo "Current CPU speed"$curspd" GHz";

choice=4

echo -e "Choose your warrior and write your own destiny : \c"

}

function press_enter

{

echo ""

echo -n "Hit Enter"

read

main_menu

}

main_menu

while [ $choice -eq 4 ] ; do

read choice

if [ $choice -eq 1 ] ; then

echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;

main_menu

else

if [ $choice -eq 2 ] ; then

echo ondemand | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;

main_menu

else

if [ $choice -eq 3 ] ; then

echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;
main_menu
else
if [ $choice -eq 4 ]; then
exit
else
echo -e "Do what?: \c"

I made this script on my own. Please tell me if it works.

I have a pretty cool script for searching, playing and downloading youtube videos with mpv and youtube-dl, although it's in python, but it doesn't use the youtube api. Should i post it?

Why do you guys convert png and jpeg to webm?

Some people think it's a good idea to emulate WebP by encoding VP8 WebMs with a single frame (it is not).

Why not switch-case it? And instead of creating variables with subshell instances, why just not use them in echo? - especially if they're used only once...

My current project has a 220-line bash build script for Linux and macOS. Thanks to ShellCheck, it was almost pleasant to write and debug.

You fucking nerd, that's pretty based. Already doing the memrise bash course for about a month but still only understood half of what you wrote without googling.

no webp support yet

I didn't know this was a thing and I'm not sure how to feel about it.

It's alright, nothing too 1337 but the weird part is you can only find them by googling them. They won't show up on the memrise website or app.
