Sorry, but this script does not work at all:

Code:
ABCDJ=0.5 |bc
GHIJJ=0.75 |bc
echo "1 Value of ABCDJ: ${ABCDJ}"
echo "2 Value of GHIJJ: ${GHIJJ}"
if [[ ${ABCDJ} -le 0 || ${GHIJJ} -ge 1 ]]; then
echo hello
fi
echo "3 Value of ABCDJ: ${ABCDJ}"
echo "4 Value of GHIJJ: ${GHIJJ}"

./scriptname
1 Value of ABCDJ: 
2 Value of GHIJJ: 
hello
3 Value of ABCDJ: 
4 Value of GHIJJ:

@jacobs.smith
Please post the exact and precise (to the last decimal place) range of the parameter or parameters you are trying to validate. The Shell normally deals with integers ... but there is always another way. I think that my post is the only one which works so far. The awk and perl programmers have kept quiet so far ... perhaps because we are all having difficulty visualising your computer.
Do you have any computer programming languages available on your computer - expecially any in which you have expertise?

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. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
csh(1), echo(1), ksh(1), sh(1), tr(1), wc(1), attributes(5) NOTES
The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
