The problem is quite simple. An underscore character is a valid character in a variable name. Therefore the variable $PLATFORMVAR_$SERVERVAR_contacts is blank !
We need some curly brackets to delimit the variables. This is good practice in Shell scripting anyway.
Many thanks.. As you can probably tell I'm not a script developer by trade..

thanks
eg:
#!/bin/sh

Hi all
Sorry for the basic question, but i am writing a shell script to get around a slightly flaky binary that ships with one of our servers. This particular utility randomly generates the correct information and could work first time or may work on the 12th or 100th attempt etc !.... (4 Replies)
I'm improving the way an existing script handles arrays, but the results aren't what I had in mind:

The for loop interprets the spaces... (2 Replies)

PLBIN(3plplot) PLplot API PLBIN(3plplot)NAME
plbin - Plot a histogram from binned data
SYNOPSIS
plbin(nbin, x, y, opt)
DESCRIPTION
Plots a histogram consisting of nbin bins. The value associated with the i'th bin is placed in x[i], and the number of points in the bin
is placed in y[i]. For proper operation, the values in x[i] must form a strictly increasing sequence. By default, x[i] is the left-hand
edge of the i'th bin. If opt=PL_BIN_CENTRED is used, the bin boundaries are placed midway between the values in the x array. Also see
plhist(3plplot) for drawing histograms from unbinned data.
Redacted form: General: plbin(x, y, opt) Perl/PDL: plbin(nbin, x, y, opt) Python: plbin(nbin, x, y, opt)
This function is not used in any examples.
ARGUMENTS
nbin (PLINT, input)
Number of bins (i.e., number of values in x and y arrays.)
x (PLFLT *, input)
Pointer to array containing values associated with bins. These must form a strictly increasing sequence.
y (PLFLT *, input)
Pointer to array containing number of points in bin. This is a PLFLT (instead of PLINT) array so as to allow histograms of proba-
bilities, etc.
opt (PLINT, input)
Is a combination of several flags: opt=PL_BIN_DEFAULT: The x represent the lower bin boundaries, the outer bins are expanded to fill
up the entire x-axis and bins of zero height are simply drawn. opt=PL_BIN_CENTRED|...: The bin boundaries are to be midway between
the x values. If the values in x are equally spaced, the values are the center values of the bins. opt=PL_BIN_NOEXPAND|...: The
outer bins are drawn with equal size as the ones inside. opt=PL_BIN_NOEMPTY|...: Bins with zero height are not drawn (there is a
gap for such bins).
