       ncvalidator - validates a classic netCDF file against CDF file formats


       ncvalidator [-x] [-t] [-q] [-h] file


       ncvalidator checks a netCDF file whether it conforms the classic CDF file formats.  If the
       input file is a valid NetCDF file, then a message of successful validation is  printed  on
       command-line output, for example, File "" is a valid NetCDF file.  Otherwise, a
       NetCDF error message is printed.


       -x     Repair the null-byte padding in file header. The null-byte padding is  required  by
              the  NetCDF  Classic  Format Specifications. PnetCDF enforces this requirement, but
              NetCDF has never enforced it. This option checks the  header  for  locations  where
              null  bytes  are  expected  and replaces them with null bytes if non-null bytes are
              found. The repaired file is then conformed with the specification and  allows  both
              PnetCDF  and  NetCDF  libraries  to  read  the  file  without  reporting error code
              NC_ENOTNC or NC_ENULLPAD. Noted that this repair is done in place and  users  might
              want  to  backup  the  input  file  first.  Once  the file is repaired, one may run
              ncmpidiff command to compare the contents of two files.

       -t     Turn on tracing mode, printing the progress of all successful metadata  validation.
              When an error is detected, the tracing stops at the location of the error found.

       -q     Quiet  mode  -  print nothing on the command-line output. When in quiet mode, users
              should check exit status. See below in "EXIT STATUS".

       -h     Print the available command-line options


       An exit status of 0 means the file is conform with the classic  CDF  file  format,  and  1
       means otherwise.  Note on VMS-based system, the exit status values are reversed.
