Use ifconfig (similar to Linux), but if it’s not in your user’s path:
/usr/sbin/ifconfig -a
rync files between servers with bandwidth throttling
As part of moving from one hosting provider to another, I needed to move a large amount of uploaded files to my local machine and then out to a VM on a new provider. Looking at rsync to do this, for moving the content locally first I didn’t want to eat up all my home bandwidth, so found there is a ‘bwlimit’ parameter in KB, e.g. –bwlimit=500 would limit to 500kbps:
rsync --bwlimit=[bw here in kbps] -a --progress [id]@[host]:/source/path .
Run this from the folder where you want the files to arrive what also contains folder ‘path’ (otherwise you’ll end up with path/path/[files here])

Automating ssh key passphrases on MacOS
As a reminder, here’s how to use ssh keys to access remote hosts:
Adding hosts to a ~/.ssh/config file to use different keys with different git hosts is something I find I only need to do once in a while, but I made a note here because I can never remember how this is configured:
If you are required to use passphrases with ssh keys, being prompted to enter your passphrase every time you use a key can get tiresome. On MacOS however you can automate using your passphrase with by adding:
UseKeychain yesto your ~/.ssh/config file (suggestion from this post here).
