To boot a broken openSUSE system:

Use the DVD. (I am not online when I do this but it should work either way.)

1. Select "install" at the main menu, then when you get to the menu,

2. Select "update" <- IMPORTANT! If you don't click on 'update' it will destroy your home folders at the last step. Reboot (reset is fine here) if there's any question and run the installer again.

Evaluating the root partition is ok....

KDE Utils: new.exec, shell-exec (for ENTER &amp; click on executables)

Posted 01-28-2012 at 03:08 AM by rainbowsally

[This post includes some test data showing what's wrong in KDE and a peek into the configuration files for various file types.]

Let's start with a program that writes programs. This is 'new.exec'.

file: new.exec (executable)
purpose: create a skeleton of a clickable shell program with an 'exec' extension.
Code:
#!/bin/sh

Simple C: Beyond Bash Part 1 - String lists and pipes

Posted 01-26-2012 at 08:03 AM by rainbowsally
