-append, -no_append¶

Introduction¶

The -append and -no_append options sets/clears the append flag. The out options are expected to respect this flag when opening output files. So an -append option before writing (-text, -bin, etc) should append to a currently existing file. The -no_append directs the file to be created before use which is the default.

$ wgrib2 grb2 -d 1 -append -text all.txt -no\_append -text rec.txt

The above line will append record #1 to all.txt and write record #1 to new file rec.txt

Usage¶

-append
      append to output files

-no_append
      over-write the output files
