Top Forums Shell Programming and Scripting Generate 100 Character Fixed Length Empty File Post 302493494 by cfajohnson on Wednesday 2nd of February 2011 11:07:19 PM

What do you mean by "an empty file"? If it is 100 characters or bytes long, it is not empty.

To fill it with spaces, you don't need any external command:
Code:
printf "%100s" ' ' > "$file"
