filegone - Trace why file gone (deleted or renamed). Uses Linux eBPF/bcc.
Contents
Description
This traces why file gone/vanished, providing information on who deleted or renamed the file.
This works by tracing the kernel vfs_unlink() , vfs_rmdir() , vfs_rename functions.
Since this uses BPF, only the root user can use this tool.
Examples
Trace all file gone events
# filegone
Trace file gone events caused by PID 181:
# filegone-p181Fields
TIME Time of the event.
PID Process ID that renamed/deleted the file.
COMM Process name for the PID.
ACTION action on file: 'DELETE' or 'RENAME'
FILE Filename.
Name
filegone - Trace why file gone (deleted or renamed). Uses Linux eBPF/bcc.
Options
-h Print usage message.
-p PID Trace this process ID only (filtered in-kernel).
Os
Linux
Overhead
This traces the kernel VFS file rename and delete functions and prints output for each event. As the rate
of this is generally expected to be low (< 1000/s), the overhead is also expected to be negligible. This
is from bcc.

and commentary for this tool.
Requirements
CONFIG_BPF and bcc.
