What do you mean by byte array?  A file is already an array of bytes. ;-)

Something like this (hex):
bytearray=(`od -x $filename | cut -c9- `)
echo "bytes:" ${bytearray[@]}

thanks. perfect.
I'm sending a zip file into a webservice using a curl from a bash script.

Just to add to the fun, it's not a file-upload.  it's a bytearray package in the soap message.  Fun.

That worked.
