Suppose we want clear RAM every day at 1 PM. Now it's time to call the command crontab: sudo crontab -e STEP 6 STEP 4īack in the terminal, we will write the following command to grant read / write permissions: sudo chmod 755 borraram.sh STEP 5 For this example I have saved the script inside a root home folder. Vim will save the sh file and exit to the terminal. To do this we will press 'esc' we will write : Wq and we will press Enter. Once everything is written, we save the sh file and we will exit the vim text editor. Then we will write the same command that we use to erase the RAM from the terminal. If we use the vim editor, we will have to press the 'esc' key and then the 'i' key to enter INSERT mode. In it, we will add the script: vim borraram.sh STEP 3
#Memory clean script install
To begin, we will start the terminal (Ctrl + Alt + T) and write the following command to install vim, or that everyone use their preferred editor: sudo apt-get install vim STEP 2 This task should be used only on desktops and laptops.

Now that we know how to free memory on our computers, we may want to automate the memory erasure process on a regular basis. If we clear the cache, the operating system will search for the requested resource on the disk. If it finds the resource in the cache, then the request will not hit disk. Gnu / Linux is designed in such a way that it examines the disk cache before searching the disk. This operation it can slow down the system for a few seconds, while the cache is cleared and all the resources required by the OS are loaded back into the disk cache. The option " ... Echo 0>…»Will not release anything, and the option« ... Echo 2>…»Will free only inodes and dentries. It is not recommended to use the third option « ... Echo 3>…»In production until you know what you are doing, since will clear the page cache, dentries, and inodes. If you have to clear the disk cache, " ... Echo> 3…”Is safer in a company and in equipment in the production phase since« ... Echo 1>….»Will delete only the page. You should immediately see that the RAM is freed up. The command ' threw out'does the work of writing to the file and drop_caches is clearing the cache without removing any app / service. In this way, we will be sure that all the objects that are cached are released. Then the command ' sync' going to clear the file system buffer. We are going to start the terminal (Ctrl + Alt + T) and type the following commands:

Select Task Manager, go to Processes, locate and find the programs or software that are taking the most memory and CPU usage. $mCatId = CatMap_Search($CM, $ItemRow) Įcho date("m.d.y g:i a")."\t($ITcnt / $ITtotal) Working On: ".

Any help or guidance will be appreciated. None of the script is contained in a function. I have tried setting the timeout to infinite but its definitely a memory issue.įatal error: Allowed memory size of 851443712 bytes exhausted (tried to allocate 71 bytes) I have tried unsetting the variables in order to release the memory between the loops but I still run out of memory. I am having memory issue and I have tried raising the memory limit to the max(800MB+).
#Memory clean script update
My script imports an excel file into a product database to update quantities new products etc.
