The command sudo bpftrace ${filename}
is used to run a bpftrace script with root privileges.
Here's a breakdown of the command:
-
sudo
: This is a command that allows a user to run programs with the security privileges of another user, typically the superuser (root). By usingsudo
at the beginning of the command, the subsequent command (in this case,bpftrace
) will run with elevated privileges. -
bpftrace
: This is a dynamic tracing tool for Linux that allows user-defined scripts to be written in a high-level language for tracing different events in the system, such as kernel function calls, system calls, and network events. -
${filename}
: This is a variable that represents the name of the bpftrace script file that you want to execute. The${filename}
part should be replaced with the actual name (including path, if necessary) of the script file you want to run.
So, when you run the command sudo bpftrace ${filename}
, it will execute the specified bpftrace script with root privileges, enabling the script to access and trace events that may require elevated permissions.
