ofl (1) - Linux Man Pages
- -k signalspec
- Send the given signal to all processes that match.
- Show only the PIDs of the processes that matched.
Differences to lsof/fuser
- `lsof /home/user` and `fuser /home/user` would not list processes that have a descriptor open on /home/user/subdir.
- `fuser -m /home/subdir` would automatically go down to the root of a vfsmount (e.g. /home) and list all processes, instead of limiting to /home/subdir.
