如何自動運行一長串與時間相關的CRON作業？

Question

我希望運行基於TZ=America/New_York的CRON作業列表，並避免手動（逐行）設置CRON作業，因為我的CRON作業在增加，並且我還將擁有每分鍾運行一次的PHP腳本，從API獲取數據。

這是我的[第一次]偽bash腳本嘗試，肯定會遇到一些問題，這樣做似乎不正確。

• 如何使與時間相關的CRON作業列表自動化？

• 手動CRON作業設置和測試有哪些替代方案？

• 也許，最好/可能用我所有的CRON作業編寫一個PHP文件，然后設置一個CRON作業來運行該PHP文件？

偽Bash腳本

#!/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無法識別Cron計划字符串（29 0 1 1 *）。 您可以嘗試編寫一些東西來解析它們，並決定在當前時間與模式匹配時做一些事情……但這就是Cron所做的。

不要為此使用bash； 使用Cron。
