Exit codes

whzbox maps command errors to process exit codes.

Standard exit codes

Code	Meaning
0	Success
1	Generic error
2	Authentication error
3	Provider error
4	User aborted an interactive prompt
5	No interactive terminal available for a required prompt

exec child exit codes

whzbox exec is special:

• if the child process exits non-zero, whzbox returns the same exit code
• whzbox does not print its own Error: line for that case

Example:

whzbox exec aws -- false
echo $?

The shell prints:

1
