Hi I ran bleachbit on ubuntu 18.04 using the command delete rotated logs-it says on the program that this deletes old system logs-what are these old system logs? does bleachbit delete anything important using this command?

Specifically if i did delete some log files could i break my ubuntu system? or could i make the internet browser firefox or my vpn which used openvpn unusable?

    Logs are only important if you need to refer to them. If you never have, then they're not important. Many logs are rotated (daily, weekly, monthly) to keep them small, and old logs deleted automatically. If you look in /var/log, you will see. – user535733 Jan 08 '20 at 23:18

Log rotation shoves the latest logs off the stage into an (optionally compressed) compressed archive file as discussed in man logrotate, with default settings specifying how many old logs are kept, and how often rotation happens, in /etc/logrotate.conf. Files in /etc/logrotate.d/ hold non-default settings for specific apps and files.

  • would using this delete rotated logs command on bleachbit delete files needed for ubuntu to boot up/function or other files relating to internet browsers or files needed for open vpn to work? – lampshade74 Jan 08 '20 at 23:50

    In a word, no. Been using BleachBit with various Ubuntus for about a decade with no such problem. This seems to be your real issue, is it not? If so, please rephrase your question to include that information, by clicking [edit] underneath the question. – K7AAY Jan 09 '20 at 01:05
  • so just to make sure i understand this right, the bleachbit 'rotated logs' command only deletes old logs files on ubuntu, it does not erase any other files on my computer at all -can i assume all i just wrote in this comment is true then? – lampshade74 Jan 11 '20 at 03:37
  • That is correct. – K7AAY Jan 12 '20 at 03:38
