bashreadline - Print entered bash commands system wide. Uses Linux eBPF/bcc.
bashreadline traces the return of the readline() function using uprobes, to show the bash commands that were entered interactively, system wide. The entered command may fail: this is just showing what was entered. This program is also a basic example of eBPF/bcc and uprobes. This makes use of a Linux 4.5 feature (bpf_perf_event_output()); for kernels older than 4.5, see the version under tools/old, which uses an older mechanism Since this uses BPF, only the root user can use this tool.
CONFIG_BPF and bcc.
Trace bash commands system wide: # bashreadline
TIME Time of the command (HH:MM:SS). PID Process ID of the bash shell. COMMAND Entered command.
As the rate of interactive bash commands is expected to be very low (<<100/s), the overhead of this program is expected to be negligible.
This is from bcc. https://github.com/iovisor/bcc Also look in the bcc distribution for a companion _examples.txt file containing example usage, output, and commentary for this tool.
Unstable - in development.
