linux sh : 批量编译工程的脚本模板

前言

前段时间，正在干活的时候，同事让我帮忙编译一版程序。有点顾不上。
后来想想，要写一个批量编译工程的脚本，就方便了。可以将一个系列的软件源码工程都编译出来, 将编译后的工程输出都拷贝到一个临时输出目录，也不用人管，只要编译从svn迁出的工程，都可以编译过的。等编译完了, 直接将临时输出目录给同事就可以了.
在做这个脚本时，学到了只判断文件不存在的脚本写法.

if [ ! -f ./obj_file ]
then
    echo "file obj_file not exist"
fi

整理后的批量编译工程的脚本模板

还可以整的复用性强些, 代码再规范些.
不过考虑到，每个工程的编译过程，写好了，一般都是不变的, 每新增一个新工程，用拷贝粘贴也说的过去.
