The command "journalctl --vacuum-time=${2d}" is used to manage log files in the systemd journal.
Here is a breakdown of each element in the command:
- "journalctl" is the command-line utility for querying and managing the systemd journal.
- "--vacuum-time" is an option used to remove journal files older than a specific time period.
- "${2d}" is a placeholder for the time period. In this case, it represents a duration of 2 days. The value "2d" can be replaced with "1w" for one week, "1month" for one month, and so on.
