> High-level tracing language for Linux eBPF
> More information: https://github.com/iovisor/bpftrace

- Display bpftrace version:

`bpftrace -V`

- List all available probes:

`sudo bpftrace -l`

- Run a one-liner program (e.g. syscall count by program):

`sudo bpftrace -e '{{tracepoint:raw_syscalls:sys_enter { @[comm] = count(); }}}'`

- Run a program from a file:

`sudo bpftrace {file value}`

- Trace a program by PID:

`sudo bpftrace -e '{{tracepoint:raw_syscalls:sys_enter /pid == 123/ { @[comm] = count(); }}}'`

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

`sudo bpftrace -d -e '{file value: one_line}'`
