This is quite useful for viewing files without opening them.. Saves quite a lot of time in viewing the logs 🙂

Want to see the first 5 lines of the /etc/passwd file? Pretty easy, just use the "head" command:

tail -20 /etc/passwd

Speed up gnome and change widow manager for gnome.

2010-01-13 3 min read Linux

I have been planning to do this for quite some time now. So finally I did this today. Actually I wanted to use some features of gnome like tracker and gnome-settings and quite a few other things along with running cairo-dock and still wanted the system to use less memory and faster response. It is well known fact that gnome/kde takes a lot of memory and CPU thus wanted to run some other window manager like fluxbox or blackbox. I went with fluxbox, as that suits my needs very well, so heres what I did:
