linux系统如何将一个文件同时复制多份

 1、创建测试数据 a.txt

[root@linuxprobe test]# seq 10 > a.txt
[root@linuxprobe test]# ls
a.txt
[root@linuxprobe test]# cat a.txt
1
2
3
4
5
6
7
8
9
10

 

 2、利用tee命令将文件同时复制多份  ## 只适用于小文件，因为cat命令要打开文件

[root@linuxprobe test]# cat a.txt | tee dup{1..10}.txt  ## 利用tee命令将a.txt复制十份
1
2
3
4
5
6
7
8
9
10
[root@linuxprobe test]# ls
a.txt  dup10.txt  dup1.txt  dup2.txt  dup3.txt  dup4.txt  dup5.txt  dup6.txt  dup7.txt  dup8.txt  dup9.txt
[root@linuxprobe test]# md5sum *.txt  ## 检测复制结果
3b0332e02daabf31651a5a0d81ba830a  a.txt
3b0332e02daabf31651a5a0d81ba830a  dup10.txt
3b0332e02daabf31651a5a0d81ba830a  dup1.txt
3b0332e02daabf31651a5a0d81ba830a  dup2.txt
3b0332e02daabf31651a5a0d81ba830a  dup3.txt
3b0332e02daabf31651a5a0d81ba830a  dup4.txt
3b0332e02daabf31651a5a0d81ba830a  dup5.txt
3b0332e02daabf31651a5a0d81ba830a  dup6.txt
3b0332e02daabf31651a5a0d81ba830a  dup7.txt
3b0332e02daabf31651a5a0d81ba830a  dup8.txt
3b0332e02daabf31651a5a0d81ba830a  dup9.txt

 

3、利用for循环将文件复制多份，适用于大小文件

[root@linuxprobe test]# rm dup*  ## 删除上一步测试结果
[root@linuxprobe test]# ls 
a.txt
[root@linuxprobe test]# for i in `seq 10`;do cp a.txt cp$i.txt;done  ## 利用for循环，将a.txt复制10份
[root@linuxprobe test]# ls
a.txt  cp10.txt  cp1.txt  cp2.txt  cp3.txt  cp4.txt  cp5.txt  cp6.txt  cp7.txt  cp8.txt  cp9.txt
[root@linuxprobe test]# md5sum *  ## 检测复制结果
3b0332e02daabf31651a5a0d81ba830a  a.txt
3b0332e02daabf31651a5a0d81ba830a  cp10.txt
3b0332e02daabf31651a5a0d81ba830a  cp1.txt
3b0332e02daabf31651a5a0d81ba830a  cp2.txt
3b0332e02daabf31651a5a0d81ba830a  cp3.txt
3b0332e02daabf31651a5a0d81ba830a  cp4.txt
3b0332e02daabf31651a5a0d81ba830a  cp5.txt
3b0332e02daabf31651a5a0d81ba830a  cp6.txt
3b0332e02daabf31651a5a0d81ba830a  cp7.txt
3b0332e02daabf31651a5a0d81ba830a  cp8.txt
3b0332e02daabf31651a5a0d81ba830a  cp9.txt

 

4、利用echo 、xargs 命令将文件复制多份   

[root@linuxprobe test]# rm cp*  ## 删除上一步测试文件
[root@linuxprobe test]# ls
a.txt
[root@linuxprobe test]# echo "cp1.txt cp2.txt cp3.txt cp4.txt" | xargs -n 1 cp a.txt  ## 利用echo 、xargs 复制文件多份
[root@linuxprobe test]# ls
a.txt  cp1.txt  cp2.txt  cp3.txt  cp4.txt
[root@linuxprobe test]# md5sum *  ## 检测复制结果
3b0332e02daabf31651a5a0d81ba830a  a.txt
3b0332e02daabf31651a5a0d81ba830a  cp1.txt
3b0332e02daabf31651a5a0d81ba830a  cp2.txt
3b0332e02daabf31651a5a0d81ba830a  cp3.txt
3b0332e02daabf31651a5a0d81ba830a  cp4.txt
