I have just migrated from windows and installed Red Hat Linux 7.3 that came with a book I got, Red Hat Linux bible. The installation all went fine and everything seems to be working well.

I just have a few questions,

The physical memory is very low, in fact it's 98% used, but the swap is 78% free, I have read in the book that you can increase the physical memory but it doesn't tell you how, could anyone tell me how this could be done, or would it just be better to buy more memory?

The second question is in Gnome there is supposed to be a program called grip but it's not there, I have tried searching for it and typing it in the shell but it just says 'not found' I have also looked in the RPM but it's not there either. When I installed I elected to have all the packages installed except for some of the servers like DNS and ftp servers ect as I don’t intend using them yet. Is there another way to check it's installed or a command from the shell I should be using?

My third question is are there any lists of shell commands for BASH that I could learn from, as I prefer to use the shell than a GUI or websites that have useful info?

and finally my mouse is an optical scrolling type, it works fine but I just can't get it to scroll, is there any way or setting for this? I have tried most of the settings I know of but the only thing I have seen related to mouse scrolling is the amount of lines to scroll by.

Thank you for your help and advice, it is much appreciated

You probably dont need to;what you see is normal for Linux.It makes efficient use of ram by caching it.If you run large programs the cached memory size will decrease.

Type whereis grip at a terminal.In my comp it's in /opt/gnome/bin/grip.

Command Directory

and finally my mouse is an optical scrolling type, it works fine but I just can't get it to scroll, is there any way or setting for this? I have tried most of the settings I know of but the only thing I have seen related to mouse scrolling is the amount of lines to scroll by.

Go to /etc/x11/xf86config and go to the section like the one I've pasted below:this is what the section should look like with scrolling enabled.

Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "ButtonNumber" "5"
Option "Device" "/dev/mouse"
Option "Name" "Autodetection"
Option "Protocol" "imps/2"
Option "Vendor" "Sysp"
Option "ZAxisMapping" "4 5"
EndSection

The relevant entries are the lines for "Protocol" "imps/2" and "ZAxisMapping" "4 5"
HTH:)

Thank you very much for your reply,

Your advice helped alot and worked out fine, thank you for the list of shell commands.

I still couldn't find grip so maybe it just wasn't installed or perhaps I could download it from the RedHat Linux site, it doesn't really matter, I have no real need to use it yet. If I need to burn anything I still have win98 & winME but I think now I have started learning Linux, I like Linux better than Windows!

Thanks again for your help
