Does anyone know of a document which itemises the differences between pdp unix shell and vax unix shell and/or software to convert same?

From: Ron Natalie <ron@brl-bmd> Which shell? So far... V6 SHELL: very restrictive PWB SHELL: hairy outgrowth of V6 shell, developped for 11's but now around on some VAX's BOURNE (V7) SHELL: distributed with V7, available on almost all VAX's. Mostly compatible between each machine. BOURNE (SIII) SHELL: Modified above (hopefully compatible) comes with SIII/V on VAX/PDP. Also available for 4.x BSD (I think). CSH: Berekeley wierd thing, comes with 4.x BSD. Runs on other unix's to the extent of the kernels ability to support it. Uses special BSD specific features. Going between different implementations of the same shell is easy (we even switched from the V7 to SIII Bourne shell without any pain). It is the programs that it is likely to call that are going to cause you problems. Does your /bin and /usr/bin programs function the same way between machines? Same options?
