How to Clear RAM Memory Cache, Buffer and Swap Space on Linux Editor June 28, 2016 June 6, 2015 Categories Linux Commands 95 Comments Like any other operating system, GNU/Linux has implemented a memory management efficiently and even more than that. Personally, I'm using this in my unit test TestInitialize function to clear out the memory cache for each unit test. Otherwise the cache persists across unit tests giving unintended results when trying to compare performance between 2 functions. – Jacob Morrison May 17 '17 at 19:26.
If your web development team has ever made a change to the files that comprise your live website, they may have asked you to “clear your cache” afterwards.
Well, what the heck does that mean?
(Editor's note: Updated July 2014 with new instructions.)
What is my 'cache' and why should I clear it?
Any sophisticated website you visit is actually a composition of dozens, hundreds or even thousands of files. Even websites supremely optimized for speed are likely loading tonsVs code diff tool. of files at once to display content in your browser.
Browsers try to do their part to speed up the loading process. The first time you visit a site, your browser will “save” pieces of the site. Because your browser can display the files stored in its cache much faster than it can pull fresh files from a server, the next time you visit that site, the use of cached files will help cut down page load time.
It sounds like cache is a good thing, why have you asked me to remove those saved files?
Many times web developers have to make updates to the files that comprise your site in order to push a change or new feature live. If we change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see our most recent change. That’s why we ask you to clear your cache.
How do I clear my cache?
The process of clearing cache differs from browser to browser. Generally speaking, look for an option to delete cache or temporary files in your browser’s administrative settings.

If you have Internet Explorer 9 or 10 click the gear icon in the top right.

Select only 'Temporary Internet Files.'
Click the 'Delete' button.
In Internet Explorer 7 or 8:
Go to Tools > Internet Options.
On the General Tab under Browsing History, select 'Delete Files.'
Delete Temporary Internet Files.

Looking for a shortcut?
If you’re a fan of using keyboard shortcuts to get around, Control, Shift, Delete (for Windows) or Command Shift Delete (for Mac) will open the configuration pane to clear cache in any browser.
What do I do after I’ve cleared my cache?
Remember, after clearing your cache in any browser, refresh the page you are viewing so your browser has a chance to grab the fresh files.
