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.

       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.
