Marc,
An important clue is where you said different results when run on command
line versus shell script. You might be launching a different NCL version
through the shell script. Try ncl -V (display version number) on command
line and in script.
Look for other differences. First compare ncdump -k between differing
files, just in case your format assumption is wrong. Then compare ncdump
-hs, line by line. In particular, compare dimension sizes and compression
parameters. Also look for missing variables.
Check for unexpected program abort for the process that makes the smaller
file. It is possible that you have a partially written file that is still
valid Netcdf4/HDF5, but partially empty data. Such file could possibly
match in terms of variables and dimension size, but be physically smaller.
