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
