标题: 如何将文件名拼接成一个字符串
ls /var/www/html/wp
index.php       wp-blog-header.php wp-includes       wp-signup.php
license.txt    wp-comments-post.php  wp-links-opml.php  wp-trackback.php
readme.html    wp-config.php       wp-load.php       xmlrpc.php
wc             wp-config-sample.php  wp-login.php
wp-activate.php  wp-content          wp-mail.php
wp-admin       wp-cron.php          wp-settings.php

如何将这些输出，用一个空格连接起来，赋值给x.

echo $x  将输出

index.php wp-blog-header.php  等等
