done 3</home/u0146121/test/newfiles.txt 4</home/u0146121/test/oldfiles.txt
done 3</home/u0146121/test/servers.txt
这是我的整个脚本
mv $oldfile /home/u0146121/backupfiles/$_$(date +%F)
这会正确移动文件,但会删除实际的文件名并仅添加日期。我想保留原始文件名并将当前日期添加到文件名中。
答案1
尝试mv $oldfile $dest_dir/$oldfile_$(date +%F-%T)
。
mv $oldfile /home/u0146121/backupfiles/$_$(date +%F)
$oldfile
如果您手动替换为文件名,则可以单行工作,但如果您专门引用变量$oldname
,$
将作为参数跳过$oldfile
并返回到历史记录以获取最后一个参数。
