filegone(8)

NAME
filegone - Trace why file gone (deleted or renamed). Uses Linux eBPF/bcc.

SYNOPSIS
filegone [-h] [-p PID]

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.

REQUIREMENTS
CONFIG_BPF and bcc.

OPTIONS

-h  Print usage message.

-p PID
    Trace this process ID only (filtered in-kernel).

EXAMPLES

Trace all file gone events
    # filegone

Trace file gone events caused by PID 181:
    # filegone -p 181

FIELDS

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.

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.

OS

STABILITY
Unstable - in development.
