我想在一行中使用rpm命令检查是否安装了特定的Linux包。然而，作为服务存在，它总是给我一个积极的结果，即使没有安装httpd，您能在这里指出问题吗？

rpm -qa httpd && echo "service present" || echo " service not present"

使用以下代码替换<PACKAGE_NAME>

rpm -q <PACKAGE_NAME> && echo "service present" || echo "service not present"

rpm -qa <PACKAGE_NAME> | grep <PACKAGE_NAME> && echo "service present" || echo "service not present"

示例：

rpm -qa httpd | grep httpd && echo "service present" || echo "service not present"


# Output

[root@bfa3155b8feb /]# rpm -qa httpd | grep httpd && echo "service present" || echo "service not present"
service not present
