I need a diff (or patch) manipulation utility, but unfortunately I have not found one, then I wrote one, of course, it's in Python.
#!/usr/bin/python
import sys, os
# Usage: diff-filter [-v] path1 path2 ...
# <INPUT >OUTPUT
if len(sys.argv) <= 1:
print "Usage: %s [-v] path1 path2 ... <INPUT" % \
os.path.basename(sys.argv[0])
sys.exit(1)
# some global variables
inChunk = True
strip = 1
matched = False
buffer = ''
invert = False
# to invert the filter
if sys.argv[1] == '-v':
invert = True
del sys.argv[1]
# the main filter
while True:
line = sys.stdin.readline()
if not line:
break
if line.startswith("--- ") or \
line.startswith("diff") or \
line.startswith("Binary") or \
line.startswith("Index"):
matched = False
inChunk = False
if line.startswith("diff") or \
line.startswith("Binary") or \
line.startswith("Index"):
buffer += line
continue
else:
path = line.split()[1]
slash = path.find('/')
path = path[slash+1:]
for arg in sys.argv[1:]:
if path.startswith(arg):
matched = True
break
else:
matched = False
if invert:
matched = not matched
if not matched:
buffer = ''
if inChunk:
print line,
if matched:
if buffer:
print buffer,
buffer = ''
print line,
It also can be reached by the ubuntu paste service:
Application field: if you have a big diff generated by "diff -R", and want to split it according to some seperate path or components, you can use this. Happy hacking!
When I was a fairly precious young man, the nothingness of the hopes and strivings that chases most men restlessly through life came to my consciousness with considerable vitality.
Moreover I soon discovered the cruelty of that chase, which in those years was much more carefully covered up by hypocrisy and glitterings words than is the case today.
By the mere existence of the stomach everyone was condemned to participate in that chase.

作者 Bdale Garbee 是 HP 的开源和Linux首席技术专家，同时是一位模型火箭飞行爱好者，
他和他的儿子很喜欢制作和飞行各种各样的模型火箭，但是当他们想要一款电子高度计用于探测火箭实飞高度时，却发现市面上现有的产品都是功能很有限，且依赖于专有
这篇论文描述了他们如何制作开放的硬件和软件来满足自己对于高度的好奇心，现场演示文件中包含有更详细的更强动力的火箭设计计划，并包含了照片和视频材料。
这些材料应该是任何对开放的小型嵌入式设备好奇的人们都感兴趣的。
硬件是基于ARM的，以 "TAPR Open Hardware" 协议开放，
并且完全是基于开源的设计工具实现的。
软件是以GNU工具链和很多开源库在 FreeRTOS 上实现的。
第二天的内容更多,首先是主题演讲,Jonathan还是再一次给大家讲述内核社区的工作原理,
JamesBottomley和JonathanCorbet与两位来自银行的人士在交流,你认出来了吗?再说find的action，是个很有用的工具，
对于查看目录下的所有文件，普通人常用的是ls，不带任何参数的ls，碰到有子目录的情况，就cd到子目录里面，进去只为敲个ls，再又cd回来，因为当前还是主要工作目录，需要查看哪个目录时就cd到哪儿去；进阶一点的人会用ls后接目录参数，可是ls还是只能列出一个目录，对于需要同时查看多个目录的情况可以用"ls -R"，可是它只列出了文件名，没有全路径，对于下一步的最大可能是cat或调用编辑器，有了全路径才是最有用的；
试试这个： "find -ls"
一次将目录下所有文件都以ls方式列表出来，可以是递归的方式看到所有文件的"ls -l"方式的结果，并且有了全路径，可以用鼠标双击全选中，再敲中键(就是鼠标滚轮)便会粘贴出来，C-A定位光标到达行首，加上个cat或者vim，阅读或者是编辑，一切操作都是连贯的；
在Shell应用中，对/proc/sys/或/sys/下的查看常常既有列表还需要阅读变量内容，以前的做法是：
find /proc/sys/vm -type f -ls -exec cat {} \;
或者需要监视这个变量值的变化情况，加上个watch，每隔1s重读一次：
watch -n1 'find /proc/sys/vm -type f -printf "%p\t" -exec cat {} \;'
find是一个简单而强大的工具，绝不只是如名称一般只有"查找"文件的功用，它的参数有两个基本类型：
1 | --- |
参看这个帖子来个实用的：查看文件链接，回复find命令的人是我：有人需要一些shell功能，想到了用python去写，想法不错，却没想到的是，那一段的python代码只对应了一行find命令。
