我希望运行基于TZ=America/New_York的CRON作业列表，并避免手动设置CRON作业（逐行），因为我的CRON作业正在增加，我还将拥有应该每分钟运行一次的PHP脚本来获取数据。 API。
这是我的[第一个]伪bash脚本尝试，它肯定会有几个问题，这样做似乎不对。
- 如何自动生成与时间相关的CRON作业列表？
- 手动CRON作业设置和测试有哪些替代方案？
- 也许，最好/可能用我所有的CRON作业写一个PHP文件，然后设置一个CRON作业来运行那个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

bash不理解Cron调度字符串（29 0 1 1 *）。您可以尝试编写一些内容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已经做的事情。
不要为此使用bash;使用Cron。
