This command is using the bpftrace
tool with sudo privileges.
Here is a breakdown of the command:
-
sudo
: This is a command used in Unix-like operating systems to allow a user to run programs with the security privileges of another user, usually the superuser. In this case, it is used to runbpftrace
with elevated privileges. -
bpftrace
: It is a high-level tracing language and tool for Linux that uses Extended BPF (eBPF) for efficient and dynamic system tracing.bpftrace
allows you to write scripts that gather information about the system's behavior. -
-d
: This is an option that tellsbpftrace
to run in debug mode. It helps in debugging the script or program by providing additional information regarding its execution. -
-e '${one_line_program}'
: This option specifies the bpftrace program/script that should be executed.${one_line_program}
is a placeholder that should be replaced with an actual bpftrace program. The program could be a single line of code that defines the tracing logic you'd like to execute.
Overall, this command is running bpftrace
with superuser privileges, in debug mode, and executing a bpftrace program defined by ${one_line_program}
.
