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.

recall

With no arguments, recall prints the last 20 commands given. With a numerical argument, it reruns that command from the command list. The only tricky part of this is that when you add a new commands the command numbers get shifted down by 1 for all the previous commands, so the same number will refer to different commands as you add more commands.

On Unix systems, this is no longer necessary, since the up and down cursor keys serve the same function.

Example: 


xsel:ASCA-sis1 > recall
