Bashscripts.org

Okay so I'm on typing a script for android operating system (which is almost identical in linux when using bash scripts ) but I can't make the correct script to do what I want.

There is a directory

Inside that directory there are folders that all contain this file named

So I tried changing the value of that file in all those folders by doing this but it doesn't take effect And I need it to set the value or it won't boot into the phone (I set a infinite loop so that it continuously tries to change the values of that file in all the folders, but since it won't boot until it does change it and since it won't change it, it never boots). Any help with this would be awesome

Here is my attempt at the code:



Help is appreciated

Hi

done!

thanks but i have another question.

why exactly didn't mine work?



edit: will this edited one work? I need it to check it if the values were set it will exit

because /sys/devices/virtual/bdi/179:0/read_ahead_kb is never re-read.

why do you think the script should stop when this file's content is 1024 ?

no need of an until-loop, you could do this :but I'm not sure it is useful, because the for-loop I gave previously should overwrite every read_ahead_kb file in every directory under /sys/devices/virtual/bdi

GENIUS!

I was just trying to come up with something like that I JUST like 2 seconds ago found that && means and in bash

and || means or they're conditional command operators or something like that but thanks

hey it didn't work I just tried it and the values didn't set

i fixed it it was just a little bit of adding this and that to make it work
