Sorry for re-posting, but Outlook inserted "funny" characters, now the clean version:

As an alternative to 'export PATH=3D...' you could execute the 2nd script in the same (korn)shell=20 that runs the 1st script, just use the 'dot' command:

---

#!/bin/ksh=20
# this is script-one

PATH=3D...
...
...
# execute script-two in the current shell, with the current environment =
and variables (PATH...)
. script-two # note the dot

---

But be aware of potential "side effects":=20 E.g.:
As script-two is read by the same ksh that excutes script-one, if script-two does an 'exit', it will terminate script-one too; when script-two does a 'cd' and execution reaches script-one again, you get the same thing as if script-one had done the 'cd'. Also, script-one will see all changes made=20 (working directory, environment, variables) by script-two.

It works as if script-one and script-two had been pasted together to one = script.
