我在 Ubuntu 16.04 服务器上有一个包含这些文件的目录：
-rwxrwxrwx 1 nobody nogroup 162034 Apr 1 2019 accounts.log
-rwxrwxrwx 1 nobody nogroup 2336191 Apr 17 2019 app.access.log
-rwxrwxrwx 1 nobody nogroup 109801 Apr 17 2019 app.error.log
-rwxrwxrwx 1 nobody nogroup 5530832 Mar 2 16:00 blocs.log
-rwxrwxrwx 1 nobody nogroup 8728 Mar 2 16:14 access.log
-rwxrwxrwx 0 nobody nogroup 9337 Mar 2 15:15 access.log.1
-rwxrwxrwx 1 nobody nogroup 9067 Mar 2 15:18 access.log.2
-rwxrwxrwx 1 nobody nogroup 10485699 Mar 2 14:53 access.log.3
-rwxrwxrwx 1 nobody nogroup 60801 Jan 6 09:21 access.log.4
-rwxrwxrwx 1 nobody nogroup 57034 Jan 6 09:22 access.log.5
-rwxrwxrwx 1 nobody nogroup 10485729 Jan 4 17:59 access.log.6
怎么access.log.1会有“0”个硬链接？
我该如何删除access.log.1？（rm access.log.1出现No such file or directory错误）...
