Question

If I use export variable method, the next bash shell can ignore eof(press ^D won’t exit).
But, I want the child bash could exit by press ^D.
Is there any command line option of bash could do this job?

export ignoreeof=1
exec bash  # assume this bash's pid = 1234
bash$  ^D  
bash$  Use "exit" to leave the shell.
bash$  bash  # assume this bash's pid = 2234
bash$  ^D  <--  I wish this could exit bash(pid=2234)

Answer 1

William, Thanks your hint.

exec bash -o ignoreeof # assume this bash's pid = 1234
bash$  ^D  
bash$  Use "exit" to leave the shell.
bash$  bash  # assume this bash's pid = 2234
bash$  ^D  <--  exit bash(pid=2234)
