Git

$ git rebase -i HEAD~3
# Choose `pick` for the base.
# Choose `squash` for all others
$ git push -f

Filesystems

List all attached storage devices:

$ sudo blkid

Add/Remove partitions

$ fdisk /dev/sda

Make a filesystem!

$ mkfs -t ext4 /dev/sda

Samba

Default .conf location: /etc/samba/smb.conf

To view current configuration settings

$ testparm

Load smb config files from /etc/samba/smb.conf

...

See network Samba shares

$ smbtree

WORKGROUP
      \\etc....

Samba requires each user to have a smbpasswd

sudo smbpasswd -a <user>

Security

security = user indicates all those that connect must be users on the server.

security = share still requires authentication deprecated

Functional similarity to security = share:

security = user
map to guest = Bad User

Samba as a system service

$ systemctl enable --now smbd.socket

# After editing /etc/samba/smb.conf
$ systectl restart smbd
