Run a script with arguments using crontab
提问by Rg90
I know this may have been answered earlier in various posts, but I've not been able to make this run myself.
我知道这可能已经在各种帖子中得到了较早的回答，但是我自己无法运行。
I have a bash script (service.sh)that I would like to run every minute. It needs an argument to be passed (startin this case).
我有一个 bash 脚本(service.sh)，我想每分钟运行一次。它需要传递一个参数（在这种情况下开始）。
Using another script (test.sh)I am scheduling the cron expression for the above script:
使用另一个脚本(test.sh)我正在为上述脚本安排 cron 表达式：
echo "* * * * * /opt/service.sh start" > /opt/cronForSecops
crontab /opt/cronForSecops
I can see by using crontab -lthat this is being set correctly as:
我可以通过使用crontab -l看到它被正确设置为：
* * * * * /opt/service.sh start
However, the service.shdoes not run, and I see no logs/files being created (which the service.shfile is supposed to do, when I run it normally).
但是，service.sh没有运行，并且我没有看到正在创建的日志/文件（service.sh文件在我正常运行时应该这样做）。
Can anybody please guide me on where I am going wrong?
有人可以指导我哪里出错了吗？

Try creating a simple wrapper script called /opt/start-service.shwith this content:
尝试创建一个/opt/start-service.sh使用以下内容调用的简单包装脚本：
#!/bin/sh
/opt/service.sh start
and make sure it's executable then use
并确保它是可执行的然后使用
* * * * * /opt/start-service.sh
as the crontab entry
作为 crontab 条目

I was having this same issue where I using the following crontab:
我在使用以下 crontab 时遇到了同样的问题：
0 23 * * * sudo -u myname /home/myname/bin/buildme.sh -f >> /home/myname/log.txt
And inside the bash script I was using this to get the -f option:
在 bash 脚本中，我使用它来获取 -f 选项：
while getopts ":f" opt; do
case $opt in
f)
force_full=1
;;
\?)
echo "Invalid option: -$OPTARG" >&2
;;
esac
done
So I noticed that the option wasn't being honored when I ran this through cron for some reason. Well, adding /bin/bash to the cronjob fixed it right up. The new crontab is:
所以我注意到当我出于某种原因通过 cron 运行这个选项时，这个选项没有得到尊重。好吧，将 /bin/bash 添加到 cronjob 中就修复了它。新的 crontab 是：
0 23 * * * sudo -u myname /bin/bash /home/myname/bin/buildme.sh -f >> /home/myname/log.txt
Hope it helps!
希望能帮助到你！
