Looking at the .prj file and searching http://spatialreference.org
might also be productive.
Another option is to upload it to spatialreference.org, and you can
then get it in a number of formats. This approach isn't recommended
for a lot of SRS's, but for a quick one-off sort of thing, it's pretty
handy.

I am looking for a convenient way to convert the SRS parameters from
a random shapefile.prj into proj.4 format. A command line interface
would be most helpful for a non-programmer, like me.
If you have python on your system (likely), then you can create a
python script (eg. prj2proj.py) with the following code in it, then
run "python prj2proj.py my.prj" and it'll print the proj4 equivalent
of the my.prj file.
HTH,
