Similar to the [zsh example](./zsh.md) bash can do auto-activation of sandboxes: ```bash sbox() { firejail --profile=~/.config/firejail/python-env-$1.profile --tab bash } sa() { source ~/envs/$1/bin/activate } if [ -n "$JAILED_ENV" ]; then if [ -n "$PWD_BEFORE_JAIL" ]; then cd "$PWD_BEFORE_JAIL" fi sa "${JAILED_ENV}" fi # Little helper to go upward the directory tree in search for a file. # Makes sure to use the least amount of external tools for performance. _upfind() { if [[ "$2" -eq 0 ]]; then return 1 fi [[ -e "$1" ]] && echo "$1" || _upfind "../$1" "$(($2 - 1))" } enable_sbox_if_needed() { if [ -n "$JAILED_ENV" ]; then return fi # Look into current and upward directories for sandbox file to # enable sandbox upon finding it. sandbox_file=$(_upfind ".python-sandbox" 5) if [[ "$?" -eq 0 ]]; then export PWD_BEFORE_JAIL="$PWD" sbox "$(head -n1 "$sandbox_file")" fi } _PYTHON_SANDBOX_PWD="" setPythonSandboxPrompt() { # only enable sandbox if we changed the directory or doing this for the first time if [ -z "$_PYTHON_SANDBOX_PWD" ] || [ "$_PYTHON_SANDBOX_PWD" != "$PWD" ]; then enable_sbox_if_needed _PYTHON_SANDBOX_PWD="$PWD" fi } if [[ "${PROMPT_COMMAND[*]}" != *setPythonSandboxPrompt* ]]; then PROMPT_COMMAND+=(setPythonSandboxPrompt) fi ```
