在bash脚本中运行php:错误“无法打开输入文件"；
我编写了一个简单的脚本，例如:
I made a simple script like:
#!/bin/bash
php /var/www/mysite/script1.php
php /var/www/mysite/script2.php
当我以root身份运行时:
When I run it as root like this:
bash update.sh
我收到以下错误:
Could not open input file: /var/www/mysite/script1.php
Could not open input file: /var/www/mysite/script2.php
怎么了?我尝试对我的php文件和所有文件夹使用权限777进行访问.当我在命令行中直接执行php/var/www/mysite/script1.php时，效果很好.
What is wrong ? I tried with permissions 777 on my php files and all folders to access it. When I do directly php /var/www/mysite/script1.php in my command line it works fine.
当批处理文件通过某些与Windows兼容的编辑器或其他不幸事件时，可能会将回车符添加到该行的末尾(正好在换行符)
When a batch file passes through some windows-compliant editors or other mishaps, it may happen that carriage return chars are appended to the end of the line (just before linefeed)
所以所有的行，例如这一行:
so the all the lines for instance this one:
php /var/www/mysite/script1.php
包含一个不可见的\r字符，该字符被解释为参数py php =>文件/var/www/mysite/script1.php<invisible char>的一部分.
contains an invisible \r char which is interpreted as part of the argument py php => file /var/www/mysite/script1.php<invisible char> not found.
执行以下操作:
dos2unix update.sh > newbatchfile.sh
或
tr -d "\015" < update.sh > newbatchfile.sh
(比较文件大小，如果newbatchfile较小，则问题是CR字符并已解决)
(compare file sizes, if the newbatchfile is smaller, problem was CR chars and is fixed)
