Want to find out more about these escaped codes and ANSI escape sequence color codes, here’s a good reference.
watch is a useful utility to execute a command on a timed basis, and exists in many Linux shells.
To install on MacOS with brew:
brew install watch
To repeat a command:
watch -n 1 somecommand
… to repeat the command every 1 second

pip3 install --upgrade --user awscli
The inevitable happened and while adding/removing some utils to my path, I messed up my .bash_profile and ended up with a PATH where I couldn’t run any commands.
To recover, the default PATH on MacOS should be:
export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
From here.
