TEST_2='11.2.3.5'
TEST_3='12.2.3.5'
TEST_4='13.2.3.5'
TEST_5='14.2.3.5'

print_var()
{
echo "Accessing var num $1"
echo TEST$1
#??? But How do I print the value of say TEST_1 here base on user input

}
echo -n "Please enter the var num: "
read num
print_var $num

NAME
posttek - PostScript translator for Tektronix 4014 files SYNOPSIS
posttek [-c num] [-f name] [-m num] [-n num] [-o list] [-p mode] [-w num] [-x num] [-y num] [file...] /usr/lib/lp/postscript/posttek DESCRIPTION
The posttek filter translates Tektronix 4014 graphics files into PostScript and writes the results on the standard output. If no files are specified, or if - is one of the input files, the standard input is read. OPTIONS
-c num Print num copies of each page. By default, only one copy is printed. -f name Print text using font name. Any PostScript font can be used, although the best results will be obtained only with constant width fonts. The default font is Courier. -m num Magnify each logical page by the factor num. Pages are scaled uniformly about the origin which, by default, is located at the cen- ter of each page. The default magnification is 1.0. -n num Print num logical pages on each piece of paper, where num can be any positive integer. By default, num is set to 1. -o list Print pages whose numbers are given in the comma-separated list. The list contains single numbers N and ranges N1 - N2. A missing N1 means the lowest numbered page, a missing N2 means the highest. The page range is an expression of logical pages rather than physical sheets of paper. For example, if you are printing two logical pages to a sheet, and you specified a range of 4, then two sheets of paper would print, containing four page layouts. If you specified a page range of 3-4, when requesting two logical pages to a sheet; then only page 3 and page 4 layouts would print, and they would appear on one physical sheet of paper. -p mode Print files in either portrait or landscape mode. Only the first character of mode is significant. The default mode is landscape. -w num Set the line width used for graphics to num points, where a point is approximately 1/72 of an inch. By default, num is set to 0 points, which forces lines to be one pixel wide. -x num Translate the origin num inches along the positive x axis. The default coordinate system has the origin fixed at the center of the page, with positive x to the right and positive y up the page. Positive num moves everything right. The default offset is 0.0 inches. -y num Translate the origin num inches along the positive y axis. Positive num moves everything up the page. The default offset is 0.0. EXIT STATUS
The following exit values are returned: 0 Successful completion. non-zero An error occurred. FILES
