如何将文件名拼接成一个字符串

yufeiluo

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
