如何自动 运行 一长串依赖时间的 CRON 作业？

Question

我希望 运行 基于 TZ=America/New_York 的 CRON 作业列表，并避免手动（逐行）设置 CRON 作业，因为我的 CRON 作业在增加，我也会有 PHP 脚本应该每分钟 运行 从 API 获取数据。

这是我的[第一个]伪bash脚本尝试，它肯定有几个问题，而且这样做似乎不对。

• How to make a list of time-dependent CRON jobs automated?

• What are the alternatives to manual CRON job setting and testing?

• Maybe, would it be best/possible to write a PHP file with all my CRON jobs and then set one CRON job to run that PHP file?

伪Bash脚本

#!/bin/bash

# There are three times that CRON jobs should be running:
# During pre-market exchanges
# During normal market hours
# During after hours or post-market exchanges

export TZ=America/New_York
server_name="$USER"

##Runs on live server
if [[ server_name=="em" ]]; then
    echo "CRON jobs only run on live servers ";
    exit
fi

#Market times: Before Premarket, Pre-market, Normal Market hours, Post-Market, After post market
pre_market_open=03:00
start_normal_market=09:00
end_normal_market=17:00
post_market_close=21:00

current_time=$(date '+%H:%M')
# current_time=5:23

#Read variables
IFS=: read hour_pre_market_open min_pre_market_open <<< "$pre_market_open"
IFS=: read hour_start_normal_market min_start_normal_market <<< "$start_normal_market"
IFS=: read hour_end_normal_market min_end_normal_market <<< "$end_normal_market"
IFS=: read hour_post_market_close min_post_market_close <<< "$post_market_close"
IFS=: read hour_current_time min_current_time <<< "$current_time"

#Calculate total minutes 
total_pre_market_open_min=$((10#$hour_pre_market_open*60 + 10#$min_pre_market_open))
total_start_normal_market_min=$((10#$hour_start_normal_market*60 + 10#$min_start_normal_market))
total_end_normal_market_min=$((10#$hour_end_normal_market*60 + 10#$min_end_normal_market))
total_post_market_close_min=$((10#$hour_post_market_close*60 + 10#$min_post_market_close))

total_current_time_min=$((10#$hour_current_time*60 + 10#$min_current_time))

bash 无法理解 Cron 计划字符串 (29 0 1 1 *)。您可以尝试编写一些东西来解析它们并决定在当前时间与模式匹配时执行某些操作...但这就是 Cron 已经在做的事情。

不要为此使用 bash；使用 Cron。
