Example: list-authors name/of/file

list-authors

#!/usr/bin/env bash
declare -r FILENAME=${1}
declare -r TEMPORATY=$(mktemp)

exec 3<> ${TEMPORATY}

{
  echo "/**"
  git blame --line-porcelain "${FILENAME}" |
    egrep '^author' |
    tr '\n' ' ' |
    sed 's,author ,\n,g' |
    sed -E 's,^(.+) author-mail (<[^>]+>).+$,\1 \2,g' |
    egrep -v '^$' |
    sed -E "s,Not Committed Yet <not.committed.yet>,$(git config user.name) <$(git config user.email)>,g" |
    sed 's,^, * @author ,' |
    sort -u
  echo " */"
} 1>&3

declare CLASS_DOCBLOCK=$(tr '\n' '#' < ${TEMPORATY} | sed 's,#,\\n,g')

sed -Ei "s%^(final )?class%${CLASS_DOCBLOCK}final class%g" ${FILENAME}

Se você esta no windows ou mac sem gnu coreutils você pode usar este script abaixo e terá que copiar na mão

#!/usr/bin/env bash

git blame --line-porcelain ${1} |
    egrep '^author |^author-mail' |
    sed 's,author-mail ,,g' |
    tr '\n' ' ' |
    tr '/>' '\n' |
    sort |
    egrep -v '^$' |
    uniq |
    sort -rn |
    sed -E 's, *author, * @author,g'
    sort
