No. You can read the filter rules directly from the standard input (stdin) by using the "-" (a single hyphen) instead of the rules file path. For example:
| Code Block |
|---|
|
% echo 'set edition=2; print "[centre]"; write;' | grib_filter -o out.gribgrib2 - in.gribgrib1 |
Or like this:
| Code Block |
|---|
|
% grib_filter -o out.gribgrib2 - in.gribgrib1 <<EOF
set edition=2;
print "centre=[centre] paramId=[paramId]";
write;
EOF |
This filter attempts to convert the messages in the input to edition 2, prints the originating centre and paramId and finally writes the output to disk.
