ubuntu 上装renderman的环境变量！不是 .bashrc 而是 .cshrc

Please add the following lines to your .cshrc (or other startup) file: setenv RMANTREE /opt/pixar/RenderManProServer-13.5
setenv RMSTREE /opt/pixar/RenderMan_Studio-1.0-Maya8.5
setenv RMSDOCTREE /opt/pixar/docs/RMS-1.0
setenv RMANFB it
setenv AW_LOCATION /usr/aw
setenv MAYA_LOCATION $AW_LOCATION/maya
setenv MAYA_PLUG_IN_PATH $RMSTREE/bin
setenv MAYA_SCRIPT_PATH $RMSTREE/lib/mtor/resources
setenv XBMLANGPATH "$RMSTREE/lib/mtor/resources/%B"
setenv LD_LIBRARY_PATH "$MAYA_LOCATION/lib:$RMSTREE/bin"
if ($RMSTREE == $RMANTREE) then
set path = ($path $RMANTREE/bin)
else
set path = ($path $RMSTREE/bin $RMANTREE/bin)
endif


感觉直接 把这个加到.bashrc里格式不对，如果需要改，请问如何改?
如果需要写在.cshrc里，这个文件在哪里阿？
