# Random Linux Tips (WIP)

### 1. Automatically clear cache.  
- Description: Move files older than a specific amount of time from your user's ~/.cache directory to the trash.  
- Requires: [https://github.com/PhrozenByte/rmtrash](rmtrash).  
- How-To:  
    - Add the following line to your crontab using the command "crontab -e" (or EDITOR=$editor crontab -e):  
$ 0 17 * * * /usr/bin/find ~/.cache/* -mtime +7 -exec /usr/bin/rmtrash -rf {} \;  
    - This command looks at files in ~/.cache every day at 5 p.m. and moves files older than 7 days to the trash.  
- Additionally: This can also be done using regular "rm" instead of "rmtrash".  
  
### 2. Clean systemd journal.
