find_log_file

Data_Reduction.DSN.logs.find_log_file(logdir, prefix, year, midfix, doy, suffix, max_look_back)

Find a generic log file.

Notes

Tries the current date and then work backwards as much as ‘max_look_back’ days until one is found. The pseudo-code for this is:

initialize output list to empty
count = 0 # look bad only max_look_back days
while output list is empty
  form name pattern
  if name pattern has *
    result = glob(pattern)
    if result is not empty:
      return result
    elif max_look_back exceeded:
      return empty result
    else:
      try an earlier date
  else:
    while log name == None:
      see if file exists
      if yes:
        return log name as a list
      elif max_look_back exceeded:
        return empty list
      else:
        try an earlier date
return output list
