Quickest Way to Create Text File of Specific Length

In order to perform a specific test of my new application SetACL Studio I needed a string with a length of exactly 32,739 bytes.

How to Create Such a Beast

That was the question I asked myself. I was not thrilled by the prospect of copying and pasting blocks of text in an editor until the required length had been reached.


Luckily I remembered that Perl has a function that makes such a task trivial: the ‘x’ operator. Here is what I came up with:

perl -e "print '1' x 32739" > 32739.txt

If you have Perl installed, that line can be executed from the regular Windows command line. “Perl -e” executes one command string (enclosed in double quotes). The result is then written to the file 32739.txt with the command line’s output redirection operator “>”.


Are there any other elegant ways to create a text file with one line of exactly 32,739 characters? If you know of one, please let me know by commenting below.
