Well, if "/XPmnt" is the directory and it appears in the process list as
you said, than you are tarring the whole directory followed by the a-d
subdirectories all over again. Gotta get that "/XPmnt" out of there.

I do not see how it got in there based on the tar command you state?

Try:

cd /XPmnt
tar -cvf /dev/rmt0 ./[a-d]*

/XPmnt is the directory from which we issued the tar command

ls -d [1-d]* gave me exactly what I expected (directories that start with
1-d).

                It is interesting to note that you have a /XPmnt as the
first file/directory
                name in the list of files/dirs to be backed up. Why is
that? What does a "ls
                -d [a-d]*" in the same directory reveal?

                Hi *

                I am attempting to tar all the subdirectories that begin
with the letters
                a-d. The command I used was:

                tar -cvf /dev/rmt0 [a-d]*

                Looking at the process list, it shows that the shell
expanded the arguments
                correctly:

                wbmpxdb01 / # ps -fu XPbackup
                     UID PID PPID C STIME TTY TIME CMD
                XPbackup 18312 64408 2 May 29 pts/2 33:45 tar -cvf
/dev/rmt0 /XPmnt
                brwarne clparch data ddmarqu dmbichl dmwiesn
                XPbackup 64408 72142 0 May 28 pts/2 0:00 -ksh
                wbmpxdb01 / #

                However, as I watch the output to the screen, tar is going
after every
                subdirectory.

                I have tested this using different ranges and it always
grabs all of the
                subdirectories.

                Can anyone explain why it might be doing this?

                TIA

                David
