fuser命令使用心得

fuser命令可用于查看正使用指定file, file system, socket port的进程信息。使用-k参数可将这些进程杀掉，-i则在杀掉进程前给出提示

例子：

[root@bogon ~]# fuser -k -i 80/tcp
80/tcp:              30922 30923
Kill process 30922 ? (y/N) y
Kill process 30923 ? (y/N) y

其他参数如下：

    -a        display unused files too
    -c        mounted FS
    -f        silently ignored (for POSIX compatibility)
    -i        ask before killing (ignored without -k)
    -k        kill processes accessing the named file
    -l        list available signal names
    -m        show all processes using the named filesystems
    -n SPACE  search in this name space (file, udp, or tcp)
    -s        silent operation
    -SIGNAL   send this signal instead of SIGKILL
    -u        display user IDs
    -v        verbose output
    -V        display version information
    -4        search IPv4 sockets only
    -6        search IPv6 sockets only
    -         reset options
