Hello,
Search in forum for abc shell and learned that Nielsen left ?
So,
Is there a startup file like .bashrc that is executed before the shell (SDK:C/sh) prompts ?
YES!
As said in:
https://linux.die.net/man/1/pdksh
Setenv ENV=etc:profile
Sh
And put echo "Very cool" in your profile file.
More Sincerely,
DG - Amigan
