#2What does Korn Shell offer over Bash shell, again? I've never used it, other than encountering a few legacy scripts on customer systems written in ksh that stopped working when they migrated over to RHEL/Centos7 and ksh was no longer installed by default.

#4Well the largest advantage is you can write and test scripts on Linux that will work on UN*X (like AIX) where bash does not exist. Also this works:
awk '{printf("%s %s %s %s", $1, $2, $3, $4)}' and many ksh scripts outside of Linux uses that syntax
