You can use the alias facility to access all of PATH. $AWS_SESSION_TOKEN = $( echo -n echo | jq -r '.Credentials.SessionToken' ) ) If you want to access a true shell variable, an extra is necessary to prevent its expansion by IPython: In 6: alias show echo In 7: PATH'A Python string' In 8: show PATH A Python string In 9: show PATH /usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin. $AWS_SECRET_ACCESS_KEY = $( echo -n echo | jq -r '.Credentials.SecretAccessKey' ) ) Xonsh uses a Python (not Bash) syntax, so an if statement is constructed in another way (unfortunately Im not a Python expert). $AWS_ACCESS_KEY_ID = $( echo -n echo | jq -r '.Credentials.AccessKeyId') ) Full screen reading What does xonsh mean The 'xonsh' word sounds like conch knt - a common name of a number of different sea snail or shells ( ). If you like the cheatsheet click on the repo and tweet. This is a good level of knowledge at start. It works on all Python-compatible systems, including Linux, macOS, and Windows.

Given a variable AWS_ASSUMED_ROLE that contains the output of the aws sts assume-role (a JSON string), I can write the following in bash. with some redirections: rst, standard output is redirected to the write.
