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
