In the short term, there's probably a fairly reasonable one liner you can use.
perl -MYAML -e "eval { YAML::LoadFile($ARGV[0]); }; exit($@ ? 1 : 0)
}" file.yaml
Or something similar.
In the longer term, it's more complicated, because YAML isn't
compliant with YAML the specification.
Since the "authorative" parser is libyaml, which is what YAML::XS uses
(I believe), crafting a script around that might be a better option.
