The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

alias

Alias a complicated command with a short one. For example: 


xsel >  alias cleansis "sisclean clean_method=2"
cleansis == sisclean clean_method=2


Note that the double quotes are necessary, otherwise XPI will think that clean_method is a parameter for alias, rather than part of the alias.
