    Try this, Archilles:

    :%s/^\(... \)\(...\)\( .*$\)/\1\2/

    It could be a little simpler than that, but this
    way you can really see the principles involved.
    Those are regular expressions. There's a tutorial
    on my website:

    Usually, for something like this, you'd use sed,
    the S tream ED itor. The commandline arguments are
    similar:

    sed -n 's/^\(... \)\(...\)\( .*$\)/\1\2/p' inputfile \
    > outputfile

    Check and make sure the output looks right, then:

    mv outputfile inputfile

    -----------------------------------------------------

    comp.editors is basically a vi/vim group. A bunch of
    vim fanatics pretty much dominate the group, but there
    are a lot of old pros there that still respect plain
    old vanilla vi, and they'll answer your questions if
    you persist in calling for a vi solution and are
    polite with the vim nuts.

    (Not that it isn't an excellent editor, but a lot of
    us are more-than-satisfied with vi. I'm using it here.
