for modify_process_pid in ${child_pids[@]}
do
echo "start modify process pid: ${modify_process_pid}"
./bin/watchmaker -pid $modify_process_pid -sec_delta $delay_second -nsec_delta $delay_nanosecond -clk_ids "CLOCK_REALTIME,CLOCK_MONOTONIC"
done

没有携带delay_nanosecond 环境变量会导致执行报错，我手动执行./bin/watchmaker -pid $modify_process_pid -sec_delta $delay_second -clk_ids "CLOCK_REALTIME,CLOCK_MONOTONIC 可以正常的修改时间

[hduzcc]

for modify_process_pid in ${child_pids[@]}
do
echo "start modify process pid: ${modify_process_pid}"

command="./bin/watchmaker -pid $modify_process_pid -clk_ids CLOCK_REALTIME,CLOCK_MONOTONIC"

if [ -n "$delay_second" ]; then
command+=" -sec_delta $delay_second"
fi

if [ -n "$delay_nanosecond" ]; then
command+=" -nsec_delta $delay_nanosecond"
fi

eval $command
done
