Just for the fun of it, using standard text tools:
Code:
tee >(cut -c-2 > left) <file | cut -c3- | rev | tee >(cut -c-2 | rev > right) | cut -c3- | rev > middle

NAME
hoz - file splitter that uses the hacha file format SYNOPSIS
hoz [-pvf] [-c size[K|M]] [-o outpath] inputfname ghoz DESCRIPTION
HOZ is a file splitter, which uses the same file format as the popular 'Hacha' program. OPTIONS
-c --cut cut (file->pieces) -p --paste paste (pieces->file) -v --verbose verbose output -f --force force overwrite of file when pasting -o --outpath specify an output directory -h --help print this help, then exit --version print hoz program version number, then exit USAGE
There are two basic operations: cut and paste. Cut will 'split' a file in pieces. The size of each piece is passed as an option. Each piece will have a numeric extension, starting with 0. So for instance if you 'cut' a file called 'foo.iso', the pieces will be named 'foo.iso.0', 'foo.iso.1' and so on. Paste will 'merge' these pieces and generate and exact copy of the original file. ghoz is the graphical version of hoz, which uses a GTK GUI interface. SEE ALSO
