Demonstrations of bashreadline, the Linux bpftrace/eBPF version. This prints bash commands from all running bash shells on the system. For example: # ./bashreadline.bt Attaching 2 probes... Tracing bash commands... Hit Ctrl-C to end. TIME PID COMMAND 06:40:06 5526 df -h 06:40:09 5526 ls -l 06:40:18 5526 echo hello bpftrace 06:40:42 5526 echooo this is a failed command, but we can see it anyway ^C The entered command may fail. This is just showing what command lines were entered interactively for bash to process. It works by tracing the return of the readline() function using uprobes (specifically a uretprobe). There is another version of this tool in bcc: https://github.com/iovisor/bcc
