在bash脚本中运行php:错误“无法打开输入文件"； [英] Run php in a bash script: error "Could not open input file"

问题描述

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.

推荐答案

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)
