Rebooting a Linux server unattended – twm’s blog

Posted by jpluimers on 2020/09/21

[WayBack] Rebooting a Linux server unattended – twm’s blog:

/sbin/shutdown -r now

Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

On my list of things to figure out: how to force fsck with opensuse Tumbleweed on Raspberry Pi 3

Posted by jpluimers on 2020/09/11

Hopefully the below links will eventually get me further in figuring out how to force fsck with opensuse Tumbleweed on Raspberry Pi 3.

For now, I just reinstalled an SD card (my Mac didn’t support the file systems and I did not have time and equipment with me to mount it to another opensuse based device).

Chromium/Chrome on opensuse Tumbleweed ARM notes

Posted by jpluimers on 2020/07/27

Somehow Firefox is available on ARM by default, but the crash recovery isn’t that awesome.

On my list of things to try is Chrome or Chromium. These links should help me find out if this is possible at all:

On Firefox crash recovery:

Eject USB drives / eject command – Unix & Linux Stack Exchange

Posted by jpluimers on 2020/07/20

I always thought than an umount /dev/sdX# for all partitions on /dev/sdX was enough for USB devices to be ejected, but there are three commands that (on most systems) actually power down USB drives (or USB to SD card adapters):

  • udisks --detach /dev/sdX (requires the udisks package which is obsolete)
  • eject /dev/sdX seems not to be enough on some systems; it is part of the util-linux package
  • udisksctl power-off -b /dev/sdX is equivalent to the udisks command; it is part of the udisks2 package.

These will ensure that the disk is not part of the fdisk --list output any more.

The opposite of these is sg_start, which is from the sg3_utils package.

On MacOS, you can use  diskutil eject /Volumes/<LABEL> (source: answer by efesaid on [WayBack] Eject USB drives / eject command – Unix & Linux Stack Exchange)
