在特定时间运行命令

发布于 2024-11-02 13:07:45 字数 251 浏览 7 评论 0原文

我正在尝试在特定时间运行命令。我查看了“at”命令，但我不知道如何让它工作......

这就是我所做的：

at 1843 (Enter)
php /run/this/script.php (Ctrl+D)

但是如何在 bash 脚本中执行此操作？我的意思是，我需要按 Enter 和“Ctrl+D”来设置延迟...如何在脚本中执行此操作？

任何建议都非常欢迎。

提前致谢，

I'm trying to run a command at a specific time. I've looked at the "at" command, but I don't know how to get it working...

Here's what I do:

at 1843 (Enter)
php /run/this/script.php (Ctrl+D)

But how do I do this in a bash script? I mean, I need to press enter and "Ctrl+D" to set up the delay... How to do this in a script?

Any suggestions most welcome.

Thanks in advance,

您可以将命令回显到 at 作为输入：

echo "/usr/bin/php /run/this/script.php" | at 18:43

You can echo your command into at as input:

echo "/usr/bin/php /run/this/script.php" | at 18:43

您可以尝试以下操作：

at 1843 <<_EOF_
php /run/this/script.php
_EOF_

编辑如果您想要运行 Firefox，请尝试以下操作：

at 1843 <<_EOF_
DISPLAY=:0.0 /usr/bin/firefox
_EOF_

You could try this:

at 1843 <<_EOF_
php /run/this/script.php
_EOF_

edit if what you want to do is run Firefox, try this:

at 1843 <<_EOF_
DISPLAY=:0.0 /usr/bin/firefox
_EOF_

在 bash 或 zsh 中，您可以说

at 1843 <<< 'php /run/this/script.php'

如果失败，您需要使用此处的文档：

at 1843 <<EOF
php /run/this/script.php
EOF

您可能还想查看 cron 来定期安排工作； crontab 条目看起来像

43 18 * * * php /run/this/script.php

（编辑：哎哟，有助于回忆 at 的版本。我认为这可能是本地 mod。）

In bash or zsh you can say

at 1843 <<< 'php /run/this/script.php'

Failing that, you need to use a here document:

at 1843 <<EOF
php /run/this/script.php
EOF

You might also want to look into cron for regularly scheduled jobs; the crontab entry would look like

43 18 * * * php /run/this/script.php

(EDIT: whoops, helps to recall which version of at. I think that may have been a local mod.)

我工作的系统（Ubuntu、RHEL）默认没有安装 at 命令，而且我没有安装新软件的权限，所以我使用结合 bash 和 awk 的脚本来实现at 功能如下：

#! /bin/bash

res=""
while [ ! $res ]; do

    res=$( date | awk -v hour=$1 -v min=$2 '{ 

        split($4, tmp, ":" );

        if( (tmp[1] == hour) && (tmp[2] == min) )
        {
            print "ok";   
        }
        else
        {
            print "";
        }

    }' )

done

./atReplacement.sh $HOUR $MIN; [OTHER_COMMANDS]

The at command is not installed by default to the systems I work (Ubuntu, RHEL) and I don't have permissions to install new software, so I use scripts that combine bash and awk in order to achieve the at functionality as follows:

#! /bin/bash

res=""
while [ ! $res ]; do

    res=$( date | awk -v hour=$1 -v min=$2 '{ 

        split($4, tmp, ":" );

        if( (tmp[1] == hour) && (tmp[2] == min) )
        {
            print "ok";   
        }
        else
        {
            print "";
        }

    }' )

done

./atReplacement.sh $HOUR $MIN; [OTHER_COMMANDS]
