How do u change the size of my icons?

How to change size of icons in Linux? (Fedora 15)?

• http://blog.fpmurphy.com/2011/03/customizing-the-gnome-3-shell.html ^^^Tried to follow the directions on that site. After saving my gnome-shell.css after editing the sizes, I tried the Alt + F2, then entered r. It gave me an error, had to re-log in, and every time after it would give me an error a few seconds after seeing my desktop and make me re-log in, then kick me off with an error message, then re-log in, etc, etc. My code was perfect, all I did was change some numbers for sizes of icons. The error message was very vague, Gnome just telling me there was an error. I had to re-install my Fedora 15 distro and am not happy about that. What did I do wrong?

• Answer:

  I made a Gnome Shell theme myself and you can easily make a mistake, 1 wrong character and it will fail to load. But I always had a back up available (which I needed sometimes) and when I made a mistake I used the Fedora live-CD to search for that mistake or to use the backup. Try to use the live-CD and replace the edited file with the default theme you use. If you know what exactly you have changed, you can go to a virtual console (Ctrl+Alt+F1), login, and then edit the file by typing: nano /path/to/file.txt But I think that Fedora automatically saves a backup of a document when you change it with the same name but with a tilde (~) after it in the same folder. You can use the "mv" command to replace it. (mv /path/to/gnome-shell.txt /path/to/gnome-shell.txt~) If you're not sure about the names, you can use the tab key (= auto-complete) to see the list of sub directories and documents. I don't know how to change the icon size anymore though, I changed to Arch Linux now and removed Fedora already.
