You can also do this from within Lynx, of course, using g)oto:
file://localhost/~/ [should list your login directory].  A simpler
way to check what you have before downloading something would be
to make your login dir the DEFAULT_INDEX_FILE in lynx.cfg

# DEFAULT_INDEX_FILE is the default file retrieved when the
# user presses the 'I' key when viewing any document.
# An index to your CWIS can be placed here or a document containing
# pointers to lots of interesting places on the web.

I'm assuming two thing here. . .  No, three:
1) your login directory is uncluttered enough that you can look it
   over quickly,
2) you remember to press 'i' *before* downloading, and
3) you don't already have something useful set as your DEFAULT_INDEX_FILE.

Might be nice to automate that, but simpler to create a quick, easy
way of checking for yourself [eg, the INDEX thing above].  Also,
with 'some_software_current.tar.gz' the same file-name from a different
server may actually *be* a differet file.  That's something Lynx
wouldn't be able to figure out.

Offering/making up new names, like index1.html, index2.html with
pre-existing files might be nice, but also easy to type in when Lynx
asks what name to save a file as.  [Also, names like that don't help
you identify something later.  Not by name, anyway.]

        I just remembered that I'm absent-minded.
        I mean I've lost my mind.
        I can't find it. . .
