svn diff 与 patch

生成diff文件：

svn diff > xxx.diff 

生成 patch:

同事 A 运行如下命令生成 patch:

svn diff > aaa.patch

 

应用 patch:

同事 B 运行如下命令应用 patch:

patch –p0 < ../aaa.patch

 

 

当他 review 完代码，想删除该 patch 时， 可运行：

patch –p0 -R < ../aaa.patch

man了下patch，了解了p0的含义：

-pnum  or  --strip=num
 
         Strip   the  smallest prefix  containing  num  leading
 
          slashesfrom each file name found in the patch file. A
 
         sequence  of one or more adjacentslashes is counted as
 
          a singleslash.  This controls how file namesfound  in
 
          the patchfile are treated, in case you keep your files
 
          in adifferent directory than the person who sent  out
 
          thepatch.  For example, supposing the filename in the
 
          patchfile was
            /u/howard/src/blurfl/blurfl.c
          setting-p0 gives the entire file name unmodified, -p1
          gives
            u/howard/src/blurfl/blurfl.c
 
          withoutthe leading slash, -p4 gives
             blurfl/blurfl.c
