Or rather you think that won't work, however if the common script starts with

Code:
#!/bin/sh
....

then the common code will be executed by /bin/sh.

If you want to deal with error checking you could do

Code:
#!/bin/whatevershellexceptcsh
commonCode
if test "$?" != "0"; then exit 1; fi

and for csh

Code:
#!/bin/csh
commonCode
if ( $status != 0 ) then
     exit 1
endif

then put all the fancy logic once in commonCode executed by /bin/sh as follows

Code:
#!/bin/sh
...do my checking....

How does that not solve the problem? You end up with one place in which you change your logic and can be called from different script engines.
