|  | Demonstrations of bashreadline, the Linux eBPF/bcc version. | 
|  |  | 
|  |  | 
|  | This prints bash commands from all running bash shells on the system. For | 
|  | example: | 
|  |  | 
|  | # ./bashreadline | 
|  | TIME      PID    COMMAND | 
|  | 05:28:25  21176  ls -l | 
|  | 05:28:28  21176  date | 
|  | 05:28:35  21176  echo hello world | 
|  | 05:28:43  21176  foo this command failed | 
|  | 05:28:45  21176  df -h | 
|  | 05:29:04  3059   echo another shell | 
|  | 05:29:13  21176  echo first shell again | 
|  |  | 
|  | 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). |
