I suspect behavior of setting $HOME when using sudo may differ between Linux flavors. As most modern Unix operating systems discourage using the root account and promote using sudo, I have mostly always used “sudo -s”. I expect that my shell then will reference /root as my home folder($HOME). I…
Go Format Output Column Style
Similar to this article (using python) https://blog.ls-al.com/python-output-align-by-column/ I also did a quick Golang implementation. It is not quite as done as I would like but it is reasonably close. Similar to the python article the idea is to use something like an array to store column header descriptions and a…
Go Associative Array
Jotting down my test to implement an associative array similar to as my python test here: https://blog.ls-al.com/python-dict-for-arrays/ In python I used dict and in go I used map. Output
Restic updates
If you are used to the way how easy rclone updates with a one-liner then this may help with restic also. Found it here: https://github.com/restic/restic/issues/1930 “just wanted to share a simple 4-line script to download and install the latest release of restic from Linux shell using cURL to /usr/local/bin:”

Bash Date Usage For Naming
I am recording some scripting I used to create backup classification/retention naming. It can be simplified into one function easily but I kept it like this so I can copy and paste easier which function I need. Script is pretty self explanatory but basically it takes today’s date and name…
Tar to Object Storage Using rclone
Sometimes using curl and uploading/downloading with an object storage back end will work just fine but in this case I was looking to tar straight into object storage. One option is using rclone with the rcat command. Some example below. This test was done using Oracle Cloud Infrastructure Object Storage…
SSH Tunnel Proxy Traffic and Bastion
Sometimes you need to test a protocol and only have SSH access through a bastion host. You can display X back for example firefox or you can route traffic through a SSH tunnel. Here is a couple examples: 1. Display back should be fairly common and I don’t need to…
Amazon Linux 2 Image and LAMP
I recently migrated a LAMP server from Amazon Linux to an Amazon Linux 2 image. Several reasons for why I needed this including it has systemd. More here: https://aws.amazon.com/amazon-linux-2/ High level steps around mysql database, wordpress and static html migration was pretty smooth as I have done this multiple times.…
