Bash cron作业无法像在命令行上那样执行 [英] Bash cron job doesn't execute like it does on command line

问题描述

我编写了一个bash脚本，该脚本执行python脚本以将文件写入目录，然后将该文件发送到Amazon S3。当我从命令行执行脚本时，它会完美执行，但是当我使用cron运行该脚本时，该文件将写入目录，但永远不会发送到S3。我一定对cron做错了。

I've written a bash script that executes a python script to write a file to a directory, then sends that file to Amazon S3. When I execute the script from the command line it executes perfectly, but when I run it with cron, the file writes to the directory, but never gets sent to S3. I must be doing something wrong with cron.

这是bash脚本：

#!/bin/bash

#python script that exports file to home directory
python some_script.py

#export file created by python to S3
s3cmd put /home/bitnami/myfile.csv s3://location/to/put/file/myfile.csv

$ b就像我之前说的那样，
$ b

使用 ./ bash_script.sh 手动执行可以正常工作。当我设置cron作业时，文件将写入目录，但从未发送到S3。

Like I said before, manually executing works fine using ./bash_script.sh. When I set up the cron job, the file writes to the directory, but never gets sent to S3.

我的cron作业是：

18 * * * * /home/bitnami/bash_script.sh

我不正确地使用cron？请帮忙。

Am I using cron incorrectly? Please help.

推荐答案

Cron看起来不错，但是找不到.py文件的路径。

Cron looks OK, however your path to the .py file will not be found.

您将必须添加路径或房屋，例如：

You will have to add a path or home like:

location=/home/bitnami/
python $location/some_script.py

还需要正确定位s3cmd：

Also s3cmd needs to be located correctly:

/bin/s3cmd

替代方案可能还需要先加载用户环境，然后再执行脚本以查找s3cmd的用户名/密码/ ssh密钥

Alternative might also need to load your user environment first before executing the script to find username/password/ssh key for s3cmd
