{N..M} is a shell sequence expression, which generates a numeric or char sequence between N and M (inclusive).
If your shell doesn't support it you can use seq.
I'm on a Unix 5.2 server and I want to be able to see my processes to verify they are active and which processor they are running on.

I need to search for a csv and a dat file within a for loop then output them to a log table. I can do it individually but I want them together.
See below code:

1) I want to display all the files in a directory that start with the word chapter, are followed by a digit 1,2,6,8, or 9 and end with .eps or .prn
so I came up with this

but is there a better way, i.e. combining both file types into the command?

seq
SEQ(1) BSD General Commands Manual SEQ(1)NAME
seq -- print sequences of numbers
SYNOPSIS
seq [-w] [-f format] [-s string] [-t string] [first [incr]] last
DESCRIPTION
The seq utility prints a sequence of numbers, one per line (default), from first (default 1), to near last as possible, in increments of incr
(default 1). When first is larger than last, the default incr is -1.
All numbers are interpreted as floating point.
Normally integer values are printed as decimal integers.
The seq utility accepts the following options:
-f format Use a printf(3) style format to print each number. Only the A, a, E, e, F, f, G, g, and % conversion characters are valid,
along with any optional flags and an optional numeric minimum field width or precision. The format can contain character
escape sequences in backslash notation as defined in ANSI X3.159-1989 (``ANSI C89''). The default is %g.
-s string Use string to separate numbers. The string can contain character escape sequences in backslash notation as defined in ANSI
X3.159-1989 (``ANSI C89''). The default is
.
-t string Use string to terminate sequence of numbers. The string can contain character escape sequences in backslash notation as
defined in ANSI X3.159-1989 (``ANSI C89''). This option is useful when the default separator does not contain a
.
-w Equalize the widths of all numbers by padding with zeros as necessary. This option has no effect with the -f option. If any
sequence numbers will be printed in exponential notation, the default conversion is changed to %e.
EXIT STATUS
The seq utility exits 0 on success, and >0 if an error occurs.

The seq command first appeared in Plan 9 from Bell Labs. A seq command appeared in NetBSD 3.0, and ported to FreeBSD 9.0. This command was
based on the command of the same name in Plan 9 from Bell Labs and the GNU core utilities. The GNU seq command first appeared in the 1.13
shell utilities release.
BUGS
The -w option does not handle the transition from pure floating point to exponent representation very well. The seq command is not bug for
bug compatible with the Plan 9 from Bell Labs or GNU versions of seq.
