You can use the following Bash command to dump all current environment variables into a .envrc file:

export -p | sed 's/^declare -x //' > .envrc

Explanation:

• export -p lists all exported environment variables.
• sed 's/^declare -x //' removes the declare -x prefix, leaving just VAR=VALUE pairs.
• > .envrc writes the output to the .envrc file.

If you're using direnv, ensure .envrc is loaded by running:

echo 'source_env .envrc' >> .envrc
direnv allow

Would you like to filter out specific variables (e.g., PATH, PWD)?
