Linux中的fuser实用程序是非常聪明的Unix实用程序。顾名思义，它提供了有关文件用户或当前正在使用文件或目录的过程的知识。本文介绍有关– Linux中“ fuser”命令的常用示例。
要获取有关热熔器的更多信息，请使用以下命令–
$ fuser
样本输出应如下所示–
Usage: fuser [-fMuvw] [-a|-s] [-4|-6] [-c|-m|-n SPACE] [-k [-i] [-SIGNAL]] NAME... fuser -l fuser -V Show which processes use the named files, sockets, or filesystems. -a,--all display unused files too -i,--interactive ask before killing (ignored without -k) -k,--kill kill processes accessing the named file -l,--list-signals list available signal names -m,--mount show all processes using the named filesystems or block device -M,--ismountpoint fulfill request only if NAME is a mount point -n,--namespace SPACE search in this name space (file, udp, or tcp) -s,--silent silent operation -SIGNAL send this signal instead of SIGKILL -u,--user display user IDs -v,--verbose verbose output -w,--writeonly kill only processes with write access -V,--version display version information -4,--ipv4 search IPv4 sockets only -6,--ipv6 search IPv6 sockets only - reset options udp/tcp names: [local_port][,[rmt_host][,[rmt_port]]]
fuser要获取使用当前目录的进程ID，请使用以下命令–
$ fuser .
样本输出应如下所示–

要终止所有上述进程，请使用以下命令–
$ fuser -k .
上面的命令关闭所有进程并关闭Linux计算机。
要获取具有Linux Machine进程ID的用户名，请使用以下命令-
$ fuser -u .
