I don't have any experience writing .sh files. I want to run the pvm2raw utility of this app from the Volume Library.I get the following error when running build.sh in Ubuntu 10.10. build.sh is as follows:# make commandset mmfile=V3Makefileset make=make -f $mmfileset rule=$1if ($rule == ) set rule=all // line 16if ($rule == deps) then   if ($HOSTTYPE == iris4d) $make MAKEDEPEND=CC -M OPTS=-DHAVE_CONFIG_H -DVIEWER_HAVE_DCMTK TARGET=IRIX depend   if ($HOSTTYPE == i386) $make MAKEDEPEND=c++ -M -I/usr/X11R6/include OPTS=-DHAVE_CONFIG_H -DVIEWER_HAVE_DCMTK TARGET=LINUX dependWhat's wrong there?Edit: I followed jw013's advice and installed csh. Now I get the following error:How can I solve this Undefined variable problem?
What's wrong with this csh file?
