    echo running ksh
    source ~/.kshrc;
else
    echo No rc file found for current shell

By default bash sources a file .bashrc if one exists in the current working for each "new" bash invocation. The same is true for ~.kshrc. Each "new" invocation of ksh sources the .kshrc file in the current working directory if it exists.

Per the man pages for each shell.

An example new: executing a script that has a shebang: #!/bin/bash, same for ksh
So why write a script which does exactly what default behavior of your shell already does for you? Good shell coding practice is to place a shebang on the first line, so it is clear what envoronment the shell requires. If bash is not in the PATH then #!/bin/bash will fail which is what you want.
