lsof [选项] [文件]
lsof命令用于查看你进程打开的文件，进程打开的端口（TCP、UDP），找回/恢复删除的文件，打开文件的进程。
(1).常用选项
-c <进程名> 列出指定进程所打开的文件 +D <目录> 递归列出目录下被打开的文件 -i <条件> 列出符号条件的进程（4、6、协议、：端口、@ip） -n <目录> 列出使用NFS的文件 -p <进程号> 列出指定进程号所打开的文件 -u s 列出login name或UID为s的程序
(2).实例
1)在没有任何参数时，显示当前系统已经打开的正在使用的所有文件

1.名称详解
COMMAND：进程名称
PID：进程标识符
TID：线程ID
USER：所有者
FD：文件描述符
TYPE：文件类型

2）查看指定文件相关的进程信息，即找出此文件的进程
[xf@xuexi ~]$ lsof /bin/bash COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME bash 14073 xf txt REG 8,3 964608 50350934 /usr/bin/bash bash 14119 xf txt REG 8,3 964608 50350934 /usr/bin/bash bash 14870 xf txt REG 8,3 964608 50350934 /usr/bin/bash
3）递归查询某个目录的文件信息
[xf@xuexi ~]$ lsof +D .local/share/ COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME gnome-she 8480 xf mem REG 8,3 32768 52016764 .local/share/gvfs-metadata/root-ce6a002c.log gnome-she 8480 xf mem REG 8,3 64 52016740 .local/share/gvfs-metadata/root gnome-she 8480 xf 27r REG 8,3 64 52016740 .local/share/gvfs-metadata/root gnome-she 8480 xf 33r REG 8,3 32768 52016764 .local/share/gvfs-metadata/root-ce6a002c.log nautilus- 8764 xf mem REG 8,3 32768 52016193 .local/share/gvfs-metadata/home-c8370b51.log nautilus- 8764 xf mem REG 8,3 528 52016339 .local/share/gvfs-metadata/home nautilus- 8764 xf 16r REG 8,3 528 52016339 .local/share/gvfs-metadata/home nautilus- 8764 xf 17r REG 8,3 32768 52016193 .local/share/gvfs-metadata/home-c8370b51.log gnome-sof 8814 xf 27r DIR 8,3 89 52015751 .local/share/flatpak/repo gnome-sof 8814 xf 28r DIR 8,3 6 843301 .local/share/flatpak/repo/objects gnome-sof 8814 xf 29r DIR 8,3 19 17315607 .local/share/flatpak/repo/tmp gnome-sof 8814 xf 30r DIR 8,3 6 52015800 .local/share/flatpak/repo/tmp/cache tracker-s 8875 xf 12w REG 8,3 284395 35774061 .local/share/tracker/data/tracker-store.journal evolution 8911 xf 11u REG 8,3 24576 35380 .local/share/evolution/addressbook/system/contacts.db gvfsd-met 9829 xf mem REG 8,3 32768 52016764 .local/share/gvfs-metadata/root-ce6a002c.log gvfsd-met 9829 xf mem REG 8,3 64 52016740 .local/share/gvfs-metadata/root gvfsd-met 9829 xf 8r REG 8,3 64 52016740 .local/share/gvfs-metadata/root gvfsd-met 9829 xf 9u REG 8,3 32768 52016764 .local/share/gvfs-metadata/root-ce6a002c.log
4）不使用+D选项得到与某个文件有关的进程信息的方法
