Freeing up RAM (memory) in Linux

Tags:

Very often I used to find that my Linux box(s), Fedora & Ubuntu both started reserving more RAM over a period of time since its boot. And the actual RAM left free was less.

I knew it was holding some caches for itself so that it could find the programs loading "quickly" and something like that (Sorry for my newbie language).

The most common way to free up RAM is Rebooting! But I wanted to avoid it, so did a little "googling" and I came up with an interesting solution - Tell linux to flush all the caches.

# Flush file system buffers by executing
sync;

# free page cache
echo 1 > /proc/sys/vm/drop_caches;

# free dentries and inodes
echo 2 > /proc/sys/vm/drop_caches

# free page cache, dentries and inodes
echo 3 > /proc/sys/vm/drop_caches

I've created a simple bash script, which u can download.

Quicker Multi tabbed terminal

Tags:

I always used gnome-terminal for my multi tabbed ssh browsing. I found an even better alternative, Byobu. It opens up Text based tabs (using screen) inside the same gnome-terminal / xterm / konsole / or whatever terminal that you use. Check the screenshot.

India's official OS

Tags:

India too can take a cue from Russia, who is working with Fedora guys to develop an official Russian OS. India too could save millions by by-passing the Windows licenses.
