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.
