fuser ¿É¼Ç
-u Append the user name of the process owner to each PID.
-k Kill processes accessing the file. Unless changed with -signal, SIGKILL is sent.
An fuser process never kills itself, but may kill other fuser processes.
The effective user ID of the process executing fuser is set to its real user ID before attempting to kill.
Usage: fuser [ -a | -s | -c ] [ -n SPACE ] [ -SIGNAL ] [ -kimuv ] NAME... [ - ] [ -n SPACE ] [ -SIGNAL ] [ -kimuv ] NAME...
fuser -l fuser -V Show which processes use the named files, sockets, or filesystems.
-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
