Google Chrome

[Menard]

Hello

The last version, as frequently new versions, is using rapidly my whole RAM (8 GiB) and then crashes the PC

Solution : not perfect of course
Start the system monitor tool, then process tab, and tab called "chrome --type=renderer..." or else, anyway the ones that take a lot of RAM memory as more than 100 MiB and end it

[Menard]

Ok, thanks, it is a good idea, I noticed that killing such process, fixes some problems like this, automation would be a great improvement

[nooblinx]

use chromium instead. they are same but chromium do not eat RAM!

[Menard]

No it is not the same, my policy is to avoid to install all browsers that could be not seriously supported by their team, it is generally the problem with too little market share

Chromium browser, it even doesn't exist, type "Chromium browser" in Google or else ...

No it is not the same ...

That's right, it isn't the same. Actually I think it's updated as well as Chrome is, it's made by the same people, but Chrome has much better support for some media formats you find on the Web. Better than probably anyone else.

I've also given up 'alternative' browsers, they're always based on one of the big ones anyway but they're not implemented as well. And they don't get security updates as fast as the biggies either.

I personnaly use 4 browsers : Chrome, Firefox, Opera and Brave, that are for me complementary, and also allow me to have different usages, for example Chrome is the only one where I am logged in my google account, and only when I need it, so I limit me to some common websites on it
The side effect is that it is cool with a separate home partition but I avoid to upgrade Linux when creating a new home is needed (as some say for the upgrade from 20 to 21) so I stay with 20.3 for the moment because my 4 browsers

I don't really understand

We must use the first script AND the second which is to specify which application and the limit (?) so then you specified Chrome but how for Firefox ?
I have also a problem to have scripts to work, the only one I have is in /home/user/ and without .sh I start it with the terminal by $ ./scrip

[Juan_David95]

I don't really understand

It's simple. The one that says first script is the one that does everything:

1) you create a text file with this name kill_mem.sh (so you don't get tangled). On this route /home/youruser/bin/. if the bin folder does not exist, create it

2) paste in this in the file:

Code: Select all

#!/bin/sh

numPro=$(ps aux | awk '{print $6,$2,$11}' | sort -nr|grep $1|head -1|awk '{print $2}')

while [ numPro=1 ];
do
numPro=$(ps aux | awk '{print $6,$2,$11}' | sort -nr|grep $1|head -1|awk '{print $2}')
SIZE=$(ps aux | awk '{print $2,$11,$6}' | sort -nr|grep $numPro|head -1|awk '{print $3/1024 " MB\t\t"}')
SIZEMB=${SIZE%.*}

echo "Process id ="$numPro" Size = "$SIZEMB" MB"
if [ $SIZEMB -gt $2 ];
then 
echo "size has been exceeded.\nKilling the process......"
`kill -9 $numPro`
echo "Killed the process"
sleep 10
else
sleep 1
echo "Size not exceeded"
fi

sleep 9
done

3) Save and close. you give execution permissions: right click on the file you give it where it says properties and then where it says permissions. Next to where it says run select. a selection symbol should appear

Now we are going to create the sh where we will indicate the processes to kill:

1) create a second text file you can name it exect_kill.sh
2) paste this:

Code: Select all

#!/bin/sh

cd ~/bin/

sh kill_mem.sh firefox 640 & sh kill_mem.sh TabNine 640

3) save and give execution permissions like the other.
4) you put exect_kill.sh at login. The easiest way is in applications at the start. If you have doubts about this part, ask.

Explanation: The name of the process can be found in the system monitor. If you want to verify that the name is correct, in the terminal:

Code: Select all

ps aux | awk '{print $6,$2,$11}' | sort -nr|grep firefox|head -1|awk '{print $2}'

In this second exect_kill.sh file you can control the processes you want for example:

Code: Select all

sh kill_mem.sh firefox 640 & sh kill_mem.sh TabNine 640 & sh kill_mem.sh chrome 640 & sh kill_mem.sh nemo 640

You will realize the pattern
1) sh to run the script
2) the one that does everything kill_mem.sh
3) name of process
3) 640 is the approx limit in mb to control the process: you can increase and decrease it at your convenience.
4) The operator & is to indicate that the script is executed in the background and allows the execution of the others

I hope I could help you.

Ok, thanks a lot, and so how can I start it ?

Humm, well, why don't you create the first script, as indicated above, and then the second with this simple content?

Code: Select all

#!/bin/sh

cd ~/bin/

sh kill_mem.sh firefox 640 

With this you will only be monitoring firefox. Then it is necessary to put this second script in the login, so that it starts every time you log in automatically. Do you know how to put a script at the login?

[Menard]

No I guess I don't know that

Complex solutions can lead to complex problems

[Juan_David95]

No I guess I don't know that

It is the simplest thing in the world. Look in the linuxmint menu look for "applications at startup". There you will see all the apps that start automatically when you start ssion on your pc.

Well, at the bottom there is a + button, to add you click, then you click where it says custom order and a box will appear where you will look for the sh that you want to start automatically.

I send you a screenshot



where it says navigate, there you click and look for the sh which in your case is the second script that I suggested you call exect_kill.sh, which you must create in the bin folder of your home. If the bin folder does not exist, create it and place the two scripts there. But only the second one, exect_kill.sh is the one you will set to start automatically.

Where it says name put what you want and where it says comment too, 2sec delay is fine and at the end you add and that's all.

Do not close yourself because the truth is not something difficult.

comment if you get stuck in any step.

Complex solutions can lead to complex problems

It's not really a complex solution. It is simply putting a script at the start of the system. Every linux user is used to that, it is the advantage of linux. Almost everything you can automate with a small script.

Please don't be disappointed... i've never done such a thing and I know I'm not alone.

On the contrary, Many Linux users installed Linux Mint because some Linux Mint users told them it was a new system that was user friendly meaning many application allready installed AND no need to use the command lines or complex system files edition ...

h a small script.
On the contrary, Many Linux users installed Linux Mint because some Linux Mint users told them it was a new system that was user friendly meaning many application allready installed AND no need to use the command lines or complex system files edition ...

And so it is. Linuxmint comes with almost everything out of the box.

I think it is important not to see it as something difficult, because when that is the case, the mind closes and cannot move forward. Actually in this solution you don't have to use command lines: just copy, paste, open applications at startup, which is a graphical interface and no commands.

The commands are already made in the script and it is enough to copy and paste them into a text file.

Edited: When I get free I'll try to make a video tutorial to show how easy it is.

[Juan_David95]

Ok, thanks a lot, and so how can I start it ?

As promised, here is the tutorial on how to implement the script to automatically kill processes. I only speak Spanish, so you can set the youtube subtitles in English.

After carrying out the steps, restart the pc, to verify that it is running.
