$ type compgen
compgen is a shell builtin

so new no process is started, so compgen sees the same environment
as the shell.

Refer man bash COMMAND EXECUTION ENVIRONMENT which says

"When a simple command _other_than_a_builtin_ or shell function is to be
executed, it is invoked in a separate execution environment".
