Well, it was a bit convoluted, but I created the file with Excel,
filling the right number of cells with \x55. This worked too. The
script wouldn't run for me. I got an error about a "bad interpreter".

I used this very simple little php script to make this

Or, using standard *nix tools (Note: 0x55 = ascii U):
dd bs=1k count=256 if=/dev/zero | tr '\000' U > full_of_0x55

I liked Steve Crawford's idea, a good one liner but I could not get it
to work on sunos, version (Generic_118558-35). Worked on HPUX.
Just using basic shell scripting, the following are another way of doing it.
Using bash, it can be done like this:
--- Start u.sh ---
#!/usr/local/bin/bash <- change to output of "which bash"
max=`expr 256 \* 1024`
for (( i=0; i<$max; ++i )) ; do
echo -n U <- depends on system, try print
done
--- End u.sh ---
E.g
./u.sh > losOfUs.txt
% xd losOfUs.txt | less
0000000 5555 5555 5555 5555 5555 5555 5555 5555
*
0040000
Or ksh or sh
--- Start u.sh ---
#!/bin/ksh <- change to output of "which ksh"
max=`expr 256 \* 1024`
i=0
while [ $i -lt $max ] ; do
print -n U
i=`expr $i + 1`
done
--- End u.sh ---
./u.sh > losOfUs.txt
od -x losOfUs.txt | less
0000000 0000 0000 0000 0000 0000 0000 0000 0000
*
