Help with tar

[Gregory N. Shapiro]

I am trying to make a tape archive of a directory and a file using tar
on an Encore MultiMax.  The first part comes out successful:

tar c -C /usr1 gshapiro

That dumps everything in my directory to tape.  The second part is
where I have trouble.  I want to add to that archive a single file
(/usr/spool/mail/gshapiro).  I have tried the following with no luck:

tar r -C /usr/spool/mail gshapiro
tar r /usr/spool/mail/gshapiro
tar u -C /usr/spool/mail gshapiro
tar u /usr/spool/mail/gshapiro


Does anyone have any suggestions???

					Thanks,

						Greg
