shell脚本：将文件移动到另一个目录

Question

I have a directory called directory1 to which we store some files daily.
I first try to remove the previous backup stored in directory2. Then I try to move the files in directory1 to directory2. I run the following bash script with cron but seems to fail.
What is wrong with my code?

#!/bin/sh
/bin/rm -rf /directory2/*
/bin/mv /directory1/* /directory2/

And my /etc/crontab has the following line:

0 6 * * 6 root /root/scripts/files.move.sh 

Answer 1

I don't see why your commands would fail, but the script can be made more defensive:

set -e; # bash specific, fail on error
/bin/mv /directory2 /directory3
/bin/mv /directory1 /directory2
/bin/rm -rf directory3
/bin/mkdir -p /directory1
