}Apparently the bourne shell permits a test such as

}    if [ -f abc.c def.c xyz.c ]
}
}probably by throwing away the def.c and xyz.c .  The korn

}the first file exists.
}
}Does anyone have any recommendations as to the best way to
}make these scripts palatable to the korn shell?

Try this one:


STRING=`echo *.c`
if [  "$STRING" != "*.c" ] ; then
	echo "There is a C program in this dir"
else
	echo "there is NO C program in this dir"
fi

I tried it both under /bin/sh and /bin/ksh and it works identically.
