    Quick answer, yes, you can delete your /var/log files but I'm wondering why is that folder so big?. Cheers, sigfried.

Can I delete those files ?




Yes, but do not. EMPTY them instead of deleting. Deleting files from /var/log/ requires the file to be unused and most log files are open. In theory deleting the file might crash the service that uses this log. Not a big issue unless you are hosting something that can not have downtime.



You can empty it with:



echo "" > logfile


Another note: please do not empty them without at least examining why these exists. Those logs will return and return and return. Fixing the issue that is being logged will keep those logs small.
