如何在多个设备上运行logcat？

Question

如何在多个设备上同时运行logcat？"adb logcat"命令给出错误:

error: more than one device and emulator

Answer 1

使用以下-s选项adb:

adb -s <serialnumber>

例

C:\Users\lel>adb devices
List of devices attached
192.168.198.101:5555    device
0123456789ABCDEF        device

adb -s 0123456789ABCDEF logcat
adb -s 192.168.198.101:5555 logcat

您可以grep将此功能组合在一起,以获取包含它的所有行.
一个例子是System.out

例:

 adb -s 192.168.198.101:5555 logcat | grep "System.out"

Answer 2

我认为它可能有用.我有这个脚本可以帮助我很多.它会将每个设备记录到不同的文件中.要停止记录,只需按CTRL + C.

#! /bin/bash

devices=`adb devices | grep 'device$' | cut -f1`
pids=""

for device in $devices
do
    log_file="$device-`date +%d-%m-%H:%M:%S`.log"
    echo "Logging device $device to \"$log_file\""
    adb -s $device logcat -v threadtime > $log_file &
    pids="$pids $!"
done

echo "Children PIDs: $pids"

killemall()
{
    echo "Killing children (what a shame...)"

    for pid in $pids
    do
        echo "Killing $pid"
        kill -TERM $pid
    done
}

trap killemall INT

wait
