我希望基于TZ=America/New_York运行CRON作业列表，并避免手动（逐行）设置CRON作业，因为我的CRON作业正在增加，并且我还将有应运行的PHP脚本每分钟从API获取数据。
这是我的[第一次]伪bash脚本尝试，肯定应该遇到几个问题，这样做似乎不正确。
如何自动创建与时间相关的CRON作业列表？
手动CRON作业设置和测试的替代方法有哪些？
也许，最好/可能是用我所有的CRON作业编写一个PHP文件，然后设置一个CRON作业来运行该PHP文件？
#!/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

答案 0 :(得分：4)
bash无法识别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做一些事情……但这就是Cron已经做过的事情。
请勿为此使用bash；使用Cron。
