Maybe different shells?

Since at least Ed Summers said it would be interesting to see the Python
code I alluded to earlier, I've put together a (hopefully self contained)
package with some of our basic Python MARC-21 modules.  Those interested
should find a compressed tarball at:
http://staff.oclc.org/~hickey/obib/obib.20040527.tgz.  There is a readme.txt
file in there with some minimal explanation.  I'd be interested in comments
and suggestions.  Right now this code lacks documentation, but does show
that (with care) Python can be used on bibliographic databases of tens of
millions of records.

OK, now why do some folk need the extra quoting and others don't?
(redirect vs cat doesn't matter)
