For what do we use Linux in an EPICS Training?

We use Linux PCs as terminals, to develop EPICS databases, to create graphical user interfaces, and to show what is going on at the VME computers. The Linux operating system is used in the SLS control rooms and at the beamlines as well. Therefore it is the environment which you will encounter if you use EPICS at the SLS.

As we are using only a few commands, it is not necessary that you are familar with Linux. The needed commands are listed in table 1. All other programs will be explained and are not standard Linux commands.

We will use a shell to insert commands which are then executed directly. Most of the commands are abbreviations (like in UNIX). Sometimes, you may think that the Linux developers are unable to remember commands with more than five characters. The most common commands are shorter.

The shell is case sensitive. All commands and EPICS names have to be entered the same way as shown. In general commands are in lower case. At the SLS, most EPICS names are in upper case.
