git log历史重写

该部分内容会改变历史信息，慎重使用。核弹级应用

替换邮件，作者：

1 git filter-branch-f --env-filter "GIT_AUTHOR_NAME='Newname'; GIT_AUTHOR_EMAIL='newemail';GIT_COMMITTER_NAME='Newname'; GIT_COMMITTER_EMAIL='newemail';" HEAD

 

GIT_AUTHOR_NAME,GIT_AUTHOR_EMAIL, GIT_AUTHOR_DATE,GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL,GIT_COMMITTER_DATE

 

gitfilter-branch --env-filter '

                   if test"$GIT_AUTHOR_EMAIL" = "root@localhost"

                   then

                          [email protected]

                           exportGIT_AUTHOR_EMAIL

                   fi

                   if test"$GIT_COMMITTER_EMAIL" = "root@localhost"

                   then

                          [email protected]

                           exportGIT_COMMITTER_EMAIL

                   fi

           ' -- --all

 

2 从所有提交中删除文件（包含机密信息或版权违反）

git filter-branch --tree-filter 'rm filename' HEAD(范围区间)

gitfilter-branch --index-filter 'git rm --cached --ignore-unmatch filename' HEAD

 

 

3 重写提交消息

gitfilter-branch -f --msg-filter 'sed -r "s/\[PIS-[0-9]+\]//g; s/\[TAIDOM-[0-9]+\]//g;s/XT1706/Taido/g" ' ${oldest_sha1}~1..HEAD

 

gitfilter-branch --msg-filter 'sed -e "/^git-svn-id:/d"'

 

gitfilter-branch --msg-filter 'cat && echo "Acked-by: Bugs Bunny"' HEAD~10..HEAD

 

4 重写tag名称

gitfilter-branch --tag-name-filter

 

5 单独分离该库底下的DIR子目录。即新库目录下只有DIR这个目录

gitfilter-branch -f --prune-empty --subdirectory-filter DIR 

 

6 项目根目录改成trunk子目录。放弃其它历史

gitfilter-branch --subdirectory-filter trunk HEAD -- --all

--all 重写所有的branches和tags

7 将提交设置为当前初始提交的父级，以便在当前历史后面粘贴其他历史记录.

gitfilter-branch --parent-filter 'sed "s/^\$/-p /"' HEAD

 

gitfilter-branch --parent-filter \

                   'test $GIT_COMMIT = && echo "-p " || cat' HEAD

或 echo "$commit-id $graft-id" >> .git/info/grafts

           git filter-branch $graft-id..HEAD

 

8 从历史除去“Darl McBribe”撰写的提交：

gitfilter-branch --commit-filter '

                   if ["$GIT_AUTHOR_NAME" = "Darl McBribe" ];

                   then

                           skip_commit"$@";

                   else

                           git commit-tree"$@";

                   fi' HEAD

 

skip_commit()

           {

                   shift;

                   while [ -n "$1" ];

                   do

                           shift;

                           map "$1";

                           shift;

                   done;

           }

 

10.               D--E--F--G--H

                    /         /

           A--B-----C

 

       仅重写D,E,F,G,H,不修改 A, B and C:  git filter-branch ... C..H

      仅重写E,F,G,H： git filter-branch ... C..H --not D

                                    gitfilter-branch ... D..H --not C

记住哦，git的使用经常都是左开右闭

 

11.  整个数目录变成子目录：

           git filter-branch --index-filter \

                   'git ls-files -s | sed"s-\t\"*-&newsubdir/-" |

                          GIT_INDEX_FILE=$GIT_INDEX_FILE.new \

                                   gitupdate-index --index-info &&

                    mv"$GIT_INDEX_FILE.new" "$GIT_INDEX_FILE"' HEAD
