In what folders are the logs and key histories stored so that I may make a script to purge them. Is there a specific folder for the hibernation partition or a file by which it keeps the RAM data on hibernate? Is someone wanted to get rid of all command history/program load history/program execution history, where would they go?
There are a lot of places where things get logged, and it will be very diffucult to be exhaustive, depending on what applications you use. That said, here are the main places I can think of:
- most system logs go into
- firefox stores your history, cookies, etc... in
~/.mozilla/firefoxThis can be purged from Firefox (shift+ctrl+suppr)
- zeitgeist is an history daemon, that populates the dash recent history. It can be purged from the privacy settings
- terminal command history is saved on a per-user basis in
~/.bash_historyDeleting this file will remove this history.
- gnome applications (gedit, nautilus, etc...) store recently used files in
~/.local/share/recently-used.xbelThis file can be deleted if needed.
These are the main places I can think of, but any application can log things in various places... so it really depends on what logs you want to remove.
As mentionned by MrVaykadji, BleachBit is a GPL software that automates such cleansing task, and let you delete "log files" for a wide variety of known softwares. You can also easily add new cleaners with simple xml files. Might be what you are (ware) looking for!
Your bash history file is in your home directory:
Zeitgeist user history is stored in
To reset the Zeitgeist history, open a terminal and copy/paste the following commands:
Or navigate to that directory in Nautilus or your file manager and manually delete the sqlite database "activity.sqlite". It will be created again by Zeitgeist minus your previous user history.
I do not feel comfortable telling users to use some commands unless they understand the command completely and are careful to double check that the command is written correctly, especially any command beginning with rm since a user could easily do irreparable damage to their system if the command was incorrectly formatted, but to better answer the OP's question as suggested in comments, the system logs are stored in
But I have heard of people causing problems by deleting subdirectories inside the log directory
as is mentioned here Can I delete /var/log files due to low root space?
But keep in mind that if you need to troubleshoot some system problem the logs will be very useful.
You can delete the contents of the journal folder by opening a terminal and copy and paste the following command:
sudo rm /var/log/journal/*
To see how much space it is using on your computer you can open a terminal and issue the query:
My system is currently is using 3.9GB.
It has to be taken under consideration that other than the logs mentioned above, many (if not most) applications keep their own individual logs in different locations. So as mentioned by alci, the answer really depends on what you want to sanitize.
Also it would be wise that, if the need does really exist you may want to try out your script writing skills to automate based on actual, specific needs of log sanitizing.
