使用“lsof”，我可以检查打开文件的列表，是否有任何命令或任何其他方式可以检测文件被访问的位置。“lsof”命令的输出如下：-
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
init 1 ??? cwd ??? ??? ??? ??? /proc/1/cwd (readlink: Permission denied)
init 1 ??? exe ??? ??? ??? ??? /proc/1/exe (readlink: Permission denied)
init 1 ??? root ??? ??? ??? ??? /proc/1/root (readlink: Permission denied)
init 1 ??? FDS /proc/1/fd/ (opendir: Permission denied)
init 2 ??? cwd ??? ??? ??? ??? /proc/2/cwd (readlink: Permission denied)
init 2 ??? exe ??? ??? ??? ??? /proc/2/exe (readlink: Permission denied)
init 2 ??? root ??? ??? ??? ??? /proc/2/root (readlink: Permission denied)
init 2 ??? FDS /proc/2/fd/ (opendir: Permission denied)
init 3 ??? cwd ??? ??? ??? ??? /proc/3/cwd (readlink: Permission denied)
init 3 ??? exe ??? ??? ??? ??? /proc/3/exe (readlink: Permission denied)
init 3 ??? root ??? ??? ??? ??? /proc/3/root (readlink: Permission denied)
init 3 ??? FDS /proc/3/fd/ (opendir: Permission denied)
init 4 ??? cwd ??? ??? ??? ??? /proc/4/cwd (readlink: Permission denied)
init 4 ??? exe ??? ??? ??? ??? /proc/4/exe (readlink: Permission denied)
init 4 ??? root ??? ??? ??? ??? /proc/4/root (readlink: Permission denied)
init 4 ??? FDS /proc/4/fd/ (opendir: Permission denied)
init 5 ??? cwd ??? ??? ??? ??? /proc/5/cwd (readlink: Permission denied)
init 5 ??? exe ??? ??? ??? ??? /proc/5/exe (readlink: Permission denied)
init 5 ??? root ??? ??? ??? ??? /proc/5/root (readlink: Permission denied)
init 5 ??? FDS /proc/5/fd/ (opendir: Permission denied)
init 6 ??? cwd ??? ??? ??? ??? /proc/6/cwd (readlink: Permission denied)
init 6 ??? exe ??? ??? ??? ??? /proc/6/exe (readlink: Permission denied)
init 6 ??? root ??? ??? ??? ??? /proc/6/root (readlink: Permission denied)
init 6 ??? FDS /proc/6/fd/ (opendir: Permission denied)
init 7 ??? cwd ??? ??? ??? ??? /proc/7/cwd (readlink: Permission denied)
init 7 ??? exe ??? ??? ??? ??? /proc/7/exe (readlink: Permission denied)
init 7 ??? root ??? ??? ??? ??? /proc/7/root (readlink: Permission denied)
init 7 ??? FDS /proc/7/fd/ (opendir: Permission denied)
init 8 ??? cwd ??? ??? ??? ??? /proc/8/cwd (readlink: Permission denied)
init 8 ??? exe ??? ??? ??? ??? /proc/8/exe (readlink: Permission denied)
init 8 ??? root ??? ??? ??? ??? /proc/8/root (readlink: Permission denied)
init 8 ??? FDS /proc/8/fd/ (opendir: Permission denied)
init 9 ??? cwd ??? ??? ??? ??? /proc/9/cwd (readlink: Permission denied)
init 9 ??? exe ??? ??? ??? ??? /proc/9/exe (readlink: Permission denied)
init 9 ??? root ??? ??? ??? ??? /proc/9/root (readlink: Permission denied)
init 9 ??? FDS /proc/9/fd/ (opendir: Permission denied)
init 10 ??? cwd ??? ??? ??? ??? /proc/10/cwd (readlink: Permission denied)
对于每个 pid，我得到三个位置，例如 pid "9"，我得到以下位置：- "/proc/1/cwd (readlink: Permission denied)","/proc/9/exe","/proc/ 9/fd/ (opendir: 权限被拒绝)"
现在我怎么知道哪个文件正在被使用？我是新手，所以不太了解。任何建议都会对您有很大帮助。
