Getting "zsh:1: command not found: aws" when uploading data to Amazon S3 from Local MacOS Machine

Hello,

I am following the guide in Transfer Data to Amazon S3 Buckets and Access Data Using MATLAB Datastore

I am using macOS 14.1.1 (23B81). I have downloaded and installed AWS Command Line Interface tool for MacOS, but when I use the command !aws or aws, I get the error:

zsh:1: command not found: aws

When I run aws --version on Terminal I get:

% aws --version

aws-cli/2.13.38 Python/3.11.6 Darwin/23.1.0 exe/x86_64 prompt/off

Any solutions or recommendations on how to troubleshoot this?

When you start up an application from icon (or dock) in MacOS, the application runs as you, but it does not go through the standard login-steps. Any additions to the shell PATH that might be done during your login steps, are simply not done. So the PATH only has the (relatively few) entries that are created for all daemons -- usually /usr/bin:/bin:/usr/sbin:/sbin

You have several choices:

• you can specify the full path to the executable when you use !, such as ! /homebrew/bin/aws --version
• you can use a compound shell command that first adds in the required path, such as ! set -x PATH="$PATH:/homebrew/bin; aws --version
• You can use setenv() instead of MATLAB to set the PATH environment variable before doing the !, such as setenv("PATH", string(getenv("PATH")) + ":/homebrew/bin")
• You can modify the plist of the MATLAB executable to add the directory to PATH
• You can modify the plist of MacOS to add the directory to PATH
• You can explicitly invoke your favourite shell with the -l flag to indicate you want it to go through login procedures; for example, ! zsh -l -c "aws --version"
