mkCache.py
This code creates the Cache file every 300 seconds.
To use this Python tool continuously in the background, run it in the following way.
$ nohup python -u mkCache.py &
Add the following code, and if you login after the reboot, the program will run.
$ sudo vi ~/.profile (sleep 10 && /usr/local/bin/python /home/detchar/Cache/mkcache.py ) & # Insert this line
code in KAGRA mine
[detchar@k1det1~]$ cd /home/detchar/Cache [detchar@k1det1 Cache]$ ls K1-Cache.cache mkCache.py nohup.out
