You need to check/generate all million numbers and then filter them with file numbers. Disposing of the edge cases tersely, never the same test twice, is important in getting a clean, minimal code. This ran almost 2 minutes for me. I could get smaller using the ternary operator '? :', but I am usually a ksh guy:

Hi,
Suppose I have 3 disks c0t0d0, c0t0d1, and c0t0d2 all with the *same* VGID.
I then run:
# vgchgid /dev/rdsk/c0t0d0 /dev/rdsk/c0t0d1
(notice I *accidentally* skipped the third disk!)
How would I fix this so that all 3 disks have the same VGID again?

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
