bpftrace: Do a dry run and display the output in eBPF format.

bpftrace

$ sudo bpftrace -d -e '${one_line_program}'

try on your machine

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 run bpftrace 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 tells bpftrace 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}.
