bashreadline.bt(8) System Manager's Manual bashreadline.bt(8) NAME bashreadline.bt - Print bash commands system wide. Uses bpftrace/eBPF. SYNOPSIS bashreadline.bt DESCRIPTION bashreadline traces the return of the readline() function using uretprobes, 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 bpftrace and uretprobes. Since this uses BPF, only the root user can use this tool. REQUIREMENTS CONFIG_BPF and bpftrace. EXAMPLES Trace bash commands system wide: # bashreadline.bt FIELDS TIME A timestamp on the output, in "HH:MM:SS" format. PID The process ID for bash. COMMAND Entered command. OVERHEAD 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. SOURCE This is from bpftrace. https://github.com/bpftrace/bpftrace Also look in the bpftrace distribution for a companion _examples.txt file containing example usage, output, and commentary for this tool. This is a bpftrace version of the bcc tool of the same name. The bcc tool may provide more options and customizations. https://github.com/iovisor/bcc OS Linux STABILITY Unstable - in development.
