在bash中移动文件时添加时间戳

Question

#!/bin/bash
while read server <&3; do   #read server names into the while loop    
 if [[ ! $server =~ [^[:space:]] ]] ; then  #empty line exception
    continue
 fi   
echo "Connecting to - $server"
#ssh "$server"  #SSH login
    while read updatedfile <&3 && read oldfile <&4; do     
        echo Comparing $updatedfile with $oldfile
        if diff "$updatedfile" "$oldfile" >/dev/null ; then
            echo The files compared are the same. No changes were made.
        else
            echo The files compared are different.
            # copy the new file and put it in the right location
            # make a back up of the old file and put in right location (time stamp)
            # rm the old file (not the back up)
            #cp -f -v $newfile

                mv $oldfile /home/u0146121/backupfiles/$oldfile_$(date +%F-%T)

        fi 

    done 3</home/u0146121/test/newfiles.txt 4</home/u0146121/test/oldfiles.txt
done 3</home/u0146121/test/servers.txt

这是我的整个剧本

mv $oldfile /home/u0146121/backupfiles/$_$(date +%F)

这会正确移动文件，但会删除实际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。

试试mv $oldfile $dest_dir/$oldfile_$(date +%F-%T)。

mv $oldfile /home/u0146121/backupfiles/$_$(date +%F)如果您手动替换$oldfile为文件名，则在单行中工作，但如果您专门引用变量$oldname，$则将跳过$oldfile作为参数并返回历史记录以获取最后一个参数。
