# 打包备份文件
tar -cvzf /backup/$date.tar.gz /backup/$date

# 删除原始备份文件
rm -rf /backup/$date

# 删除7天前的备份文件
find /backup -mtime +7 -type f -delete

By learning script programming, you can hand over tedious repetitive operations to scripts to improve work efficiency and accuracy.

Conclusion:
By mastering basic knowledge, in-depth understanding of network knowledge and learning script programming, you can achieve salary breakthroughs in the field of Linux operation and maintenance.
