dd命令可以用来创建任意大小文件,如:
在当前目录下创建一个文件名为file的10M的空文件
dd if=/dev/zero of=./file.txt bs=1M count=10
下面为一个脚本,可以创建指定数量、大小和名称的文件(蓝色部分为脚本内容)
linux:/mnt/hgfs/vmware-share/dd # cat test.sh
#!/bin/bash
count=0
MAX=10
FileName='file'
while [ ${count} -lt ${MAX} ]
do
#echo ${count}
tmp=${FileName}${count}
#echo ${tmp}
dd if=/dev/zero of=./${tmp} bs=1M count=10
((count++))
done
