# Getting System Information and Logs

## Display Information in Memory

* `free` command display information on memory
* `df` command for disk free\* reports on the available disk space on each of the mounted disks
* `id` command displays the identity of the user running the session along with a list of groups they belong to
* `uname -a` returns a single line documenting the kernel name (`Linux`), the hostname, the kernel release, the kernel version, the machine type (an architecture string such as `x86_64`), and the name of the operating system (`GNU/Linux`).  The output of this command should be included in bug reports as it clearly defines the kernel in use.

## Display Kernel Logs

* `dmesg` retrieves kernel logs
* `journalctl` stores multiple logs from services, syslog, and kernal logs
