Install AWS CLI v2 from source

Bash script to install the latest released version of the AWS CLI v2 from the distrubuted source.

Using this method to exectue the CLI under a MacBook M1 laptop as a native ARM binary - rather than falling back to Rosetta. Currently the offically packaged macOS .pkg doesn't support both Intel/M1 architectures.

Script designed to be re-run - will blow away an existing install and re-install the latest available version.

Note

This install script assumes you have installed a suitable version of Python 3 - has been tested against Python 3.10.11 under macOS Sonoma v14.6.1.

After 2024-04-02 I am only adding important new discoveries (I come accross). There is just too much Blog and Video entries to keep track of.

FAQ on the xz-utils backdoor (CVE-2024-3094)

Manually fixing bit flips in BTRFS

Somehow my BTRFS file system became corrupted by what appears to be a single bit flip in a metadata field. Rather than copying all the data and reformatting the file system, which would have required another disk at least as large as the original, I decided to try to fix this manually, which appears to have worked. I've documented the procedure I've used here, in case I need it again or someone else runs into a similar issue and finds it useful.

The first thing you should do is run btrfs check. For me this produced the following output:

Opening filesystem to check...
