Hi,

for future users:

useradd -D -s /usr/bin/ksh

For existing users:

usermod -s /usr/bin/ksh userid

usermod -s /usr/bin/ksh username
This will modify the user's (reflected as username) from what it is to /usr/bin/ksh

useradd -D -s /usr/bin/ksh
To alter the default shell for future users.

Explanation:

The first command will modify the file /etc/default/useradd to set ksh as the default for newly created users.

The second command will modify /etc/passwd to set the shell for existing users.

useradd -D will display existing defaults.

bash is the default on pretty much all Linux systems as most Linux distros don't include ksh in their default install.

Also, bash and ksh are 99% compatible, so there's really not a huge difference between the two unless you are using some very, very advanced/obscure features of ksh.

There's nothing obscure in ksh.

Perhaps Greensburo just doesn't like this old pipe/subshell problem (Remember? Reassigning variables using a pipe and e.g read?)

If his bash is <  4.2 not even the "shopt -s lastpipe" workaround is available.
