[SHELL]用于快速搜索C++/C/JAVA/汇编等源代码的SHELL脚本

 

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):"
