internal of the file, line is ascending, but the files is descending. so we need to rename files by time ascending. The expection like these, assumption 3 files.

logcat.log -> logcat.03.log
logcat.log.1 -> logcat.02.log
logcat.log.2 -> logcat.01.log

usage

  578  python logcat_rename.py --logcat-dir=/disk2/thomas/sjPBP/DMS/GRACE-89/03/Log.2/

After that the filenames will be these:
