00-start.py

The IPython startup script

~/.config/ipython/profile_spockdoor/startup/00-start.py

is used to:

• create a ipython_log.py for each spock session, in PWD and /online_dir
• executes MotorLogger.py
• executes Macros on a Door
• defines useful aliases

To purge versioned files:

$ vrsn       

  Usage: 

    Display all versions:              # vrsn file_name 

    Create a new version:              # vrsn -s file_name

    Purge, keeping nk (def 2):         # vrsn -p [nk] file_name 

    Rename the files, starting from 1: # vrsn -reset file_name 

    -nolog is optional, suppresses informational output
