Question

我写了一个脚本，任务是创建一个文本文件并写成两行。

这已经完成，但不止一次，我不明白为什么因为脚本文件不包含任何循环和文件执行后。

#!/bin/bash

<other, non-relevant variables and commands>

PHP_ROOT_DIR=/etc/php-5.6.22
PHP_CGI_WRAPPER=php-5622

mkdir -p $(dirname $0)/cgi-bin
touch $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
echo -e "#!/bin/bash" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
echo -e "exec ${PHP_ROOT_DIR}/bin/php-cgi" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER

<other, non-relevant variables and commands>

exit 0

输出文件内容：

#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi
#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi
#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi

更新

运行Docker容器时会出现此结果。

如果我将脚本减少到上面的部分（删除了不相关的代码部分），那么在容器中的主机操作系统和Docker上正常工作。

但问题仍然没有解决。

完整版脚本文件是这样的：

#!/bin/bash

source $(dirname $0)/create_vhost_config.sh
source $(dirname $0)/create_sample_html.sh

IP=$(ip route get 1 | awk '{print $NF;exit}')

SRC_DIR=/usr/local/src

HTTPD_VERSION=2.4.20
HTTPD_ROOT_DIR=/etc/apache2
HTTPD_CONF_FILE=/etc/apache2/conf/apache2.conf

PHP_VERSION=5.6.22
PHP_ROOT_DIR=/etc/php-5.6.22
PHP_CGI_WRAPPER=php-5622

改变这个：

int main () { unsigned int x [4] [3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}, {10, 11, 12}}; printf("%u, %u, %u", x + 3, * (x + 3), * (x + 2) + 3); }

到此：

echo -e "#!/bin/bash" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
