[SHELL]用于快速搜索C++/C/JAVA/汇编等源代码的SHELL脚本 博客分类： linux_app
面对动不动10多G容量的android源码目录，想要在这个源码目录里搜索一个 字符串，或者想要知道某个函数的定义，实在太难了，尤其是没有目的的搜索，速度是很慢的。但时间是弥足珍贵的，效率是必须提升的，我们总不能继续沦为更底层的码农吧，哈哈。这个脚本就是帮助大家从搜索源码的禁锢当中解脱的。
使用方法：
$ chgrep
please append 2 args behind the chgrep!
Help(Example):
chgrep <file_type> <find_in_sub_dir> <grep_string> [grep_options]
chgrep ch mediatek/ blacklight :is finding blacklight in *.c *.h files in mediatek dir
<file_type>:: ch: *.c,*.h; cpph ;cc;ch+k;java;asm; ccj: cpp,h,c,java; log: *.log *.txt; mk: mk,Makefile..;
示例：
chgrep ccj mediatek,hardware,system,frameworks/ "notifyPixelsChanged" -iw
上面这个示例的含义是，在当前目录下的 “mediatek,hardware,system,frameworks” 4个子目录中寻找 C/C++/JAVA代码，并在这些代码里查找 "notifyPixelsChanged" 字符串。
-i 的意思是 不区分大小写， -w的意思是 全字匹配。只要是 grep命令的参数，都可以用在这里。
比如 -n ，可以在搜索结果显示出找到关键词的行号。
脚本内容如下：
$ cat ../runsh/chgrep
#!/bin/bash
#curr_dir=$(pwd)/
ign_case=$4
#echo $curr_dir
sear_dirs=${2//','/' '}
echo Sear_dirs:$sear_dirs
search_dirs=($sear_dirs)
echo search_dirs:$search_dirs
if [ $# -lt 3 ]; then
echo "please append 2 args behind the chgrep!"
echo "Help(Example):"
