Now i'm using a python code to bypass the problem
start_capture:
#!/usr/bin/env python3
import subprocess
process = subprocess.Popen(["tshark", "-i", "lo", "-f", "udp"])
with open("{{ CAPTURE_PATH }}.pid", "w") as out:
out.write(str(process.pid))
from just.
You can also use a shell shebang do bypass the problem.
In a normal Just recipe, each line is run in its own shell, so you can't refer to variables set in previous lines. Shebang recipes run the entire body through the selected interpreter. This should also work for you:
start_capture:
#!/bin/sh
tshark -i lo -f udp &
echo $! > PATH.PID
from just.
