How to install .run files
 

I'm downloading Wolfenstein Enemy territory, and It will be finished in about an hour. It ends as a .run file. What is the command in the x console to start the installation?

well you may have to make it executable first, so type :
chmod +x nameoffile.run
and then type :
./nameoffile.run

or just use:

bash filename.run

*.run files are essentially scripts with data attached.

since this is on topic what do i do if i get
ERROR: Unable to find the system utility `ld`; please make sure you have the
package 'binutils' installed. If you do have binutils installed,
then please check that `ld` is in your PATH.

You need to use one of 2 possible solutions to your problem;

1) make sure that binutils is installed on your system (I can't beleive it wouldn't be). If you use an RPM based system such as RedHat, Fedora, SuSE, or Mandrake, use your installer program to do a search for it and make sure it's installed.

2) your ld program is either only available as root, or is not pathed so that it can be used by all users. Either way, you need to either change it's permissions or general security so that it can be used by all or install your script with a user account that has higher permissions (you may have set your security too high, for example). Alternatively, you could make a symbolic link to a path where all users have access and give all users executable permissions to the ld executable (at least temporarily). that might work.
