Ksh (Korne-Shell)

[Jas]

  While working during the summer I used ksh a lot and really liked it.
Someone told me that it was PD so I wondered if this is true and if anyone
knows where to get hold of it, or if there is something similar about?
  I'm also not sure if it will run on our Uni System V - the machine at
work was a Unix V.4.
  Any  help is appreciated,

        Jas.
