Use the following (suboptimal) script to obtain a list of possible typos: #!/usr/bin/env sh set -x git ls-files |\ grep -e '\.\(c\|cc\|go\)$' |\ xargs -n 1\ awk\ '/\/\// { gsub(/.*\/\//, ""); print; } /\/\*/, /\*\// { gsub(/.*\/\*/, ""); gsub(/\*\/.*/, ""); }' |\ hunspell -d en_US -l |\ grep '^[[:upper:]]\{0,1\}[[:lower:]]\{1,\}$' |\ grep -v -e '^.\{1,4\}$' -e '^.\{16,\}$' |\ sort -f |\ uniq -c |\ awk '$1 == 1 { print $2; }' Then, go through the results manually and fix the most obvious typos in the non-vendored code.
