/bin/sh: docker-php-source: not found进入当前容器，发现docker-php-source文件存在但是也无法执行~
纠结办法编辑docker-php-source文件发现惊天大秘密

#!/bin/sh^M

在linux下，不可避免的会用VIM打开一些windows下编辑过的文本文件。我们会发现文件的每行结尾都会有一个^M符号，这是因为 DOS下的编辑器和Linux编辑器对文件行末的回车符处理不一致， 
对于回车符的定义： 
windows：0D0A 
unix\linux: 0A 
MAC: 0D 
比较快捷的去除这些符号的方法有这么几种： 
（1）是用VI的命令： 
    使用vi打开文本文件 
    vi dos.txt 
    命令模式下输入 
    :set fileformat=unix 
    :w 
(2) VI下使用正则表达式替换 
   g/\^M/s/\^M// 
    或者 
   %s/^M//g 
（3）使用sed 工具 
    sed ’s/^M//’ filename > tmp_filename 
（4）既然window下的回车符多了‘\r’，那么当然通过删除‘\r’ ，也可以实现： 
    tr -d '\r' 
（5）最后一个方法是本人最常用的方法，个人觉得最方便 
    在终端下敲命令： 
    $ dos2unix filename 
    直接转换成unix格式，就OK了！～
