Create multiple empty files #

The following examples create three empty files of 1MB each:

Unix:

$ for i in {1..3}; do dd if=/dev/zero of=/path/$i bs=1m count=1; done
or,
$ for i in {1..3}; do mkfile 1m /path/$i; done

Windows:

C:\>for /L %x in (1,1,3) do fsutil file createnew %x 1048576

Notes:

mkfile can generate sparse files with the -n option.
The Windows for loop set is (start,step,end).
See also Generate Files with Random Content and Size in Bash, which introduces this script:
no_of_files=10; counter=1; while [[ $counter -le $no_of_files ]]; do echo Creating file no $counter; dd bs=1024 count=$RANDOM skip=$RANDOM if=/dev/sda of=random-file.$counter; let "counter += 1"; done
