EPICS installations at GSI - Prerequisites for GSI

1. become a member of the group epicsadm on Linux to check type groups on your prompt:
   $> groups
yourgroup(s) ... epicsadm ...
2. login to the group epicsadmin with newgrp - epicsadm (the minus is important):
   $> newgrp - epicsadm
3. change umask to ug+w to enable other members of epicsadm to edit all files you have created/modified:
   either each time
   • $> umask 002
   • or by adding the following lines to your ~/.profile or ~/.bashrc files.
     (The ' - ' in the newgrp command forces executing the loginscript)
     

           #if logged in as group epicsadm, change umask to ug+w
           if [ $(id -gn) = "epicsadm" ];
           then
              umask 002;
              # or anything else
           fi
           

4. change to ~epics:
   $> cd ~epics
5. Make the download directory, if not yet existing:
   
   $> mkdir download
