创建每个具有特定文件大小的文件目录

Question

我想创建 100 个文件，每个文件大小为 10Mb。是否有一个简单的 unix 命令可以创建一个包含这 100 个文件的目录？

Answer 1

for x in {1..100}; do dd if=/dev/zero of=file$x bs=10485760 count=1; done

if=FILE (read from FILE instead of stdin)
of=FILE (write to FILE instead of stdout)
bs=BYTES (force ibs=BYTES and obs=BYTES)
ibs=BYTES (read BYTES bytes at a time)
obs=BYTES (write BYTES bytes at a time)
count=1 (copy only 1 input block)
