    if [ "$GIT_COMMITTER_EMAIL" = "<OLD AUTHOR EMAIL - 1>" ]; then
        export GIT_COMMITTER_NAME="<NEW AUTHOR NAME>"
        export GIT_COMMITTER_EMAIL="<NEW AUTHOR EMAIL>"
    fi
    if [ "$GIT_COMMITTER_EMAIL" = "<OLD AUTHOR EMAIL - 2 ... >" ]; then

        export GIT_COMMITTER_EMAIL="<NEW AUTHOR EMAIL>"
    fi
' --tag-name-filter cat -f -- --all
