Sorry for such a dreadful title, but I'm not sure how to be more descriptive. I'm hoping some of the more gurutastic out there can take a look at a solution I came up with to a problem, and advice if there are better ways to have gone about it.

I'm trying to understand if it's possible to create a set of variables that are numbered based on another variable (using eval) in a loop, and then call on it before the loop ends.
As an example I've written a script called question (The fist command is to show what is the contents of the... (2 Replies)
Hi Im running this script, which is supposed to find the max value build some tables and then stop running once all the tables are built. Thing is , it keeps assigning a null value to $h and then $g is null so it keep building tables i.e. testupdateNUL. How can I stop this? Here is what I have:

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)
Hi,
hope I am posting in the right section.
My problem is that I have 2 or more arguments passed and I want to check if the arguments passed exists or not.
The first argument should not exist and the remaining others should exist.
example:
./shells.sh argument1 argument2 argument3

Hi, I was debating if I should put this in the dummies or scripts section, I apologize in advance if I chose poorly.
Fairly new to Unix and BASH scripting but I thought I made it fairly well given my limited understanding. However, the output indicates that it's looping and I'm ending up with a... (5 Replies)

Hi all,
i developed a script to measure the uptime of a process in a Solaris 10/11 environments.
All is well, but i came across a situation where there are multiple processes of the same name. Basically i have the following result file:

mlib_imagestddev_fp
mlib_ImageStdDev_Fp(3MLIB) mediaLib Library Functions mlib_ImageStdDev_Fp(3MLIB)NAME
mlib_ImageStdDev_Fp - image standard deviation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageStdDev_Fp(mlib_d64 *sdev, const mlib_image *img, const mlib_d64 *mean);
DESCRIPTION
The mlib_ImageStdDev_Fp() function computes the standard deviation for each channel in the floating-point source image.
It uses the following equation:
1 w-1 h-1
sdev[i] = { ----- * SUM SUM (img[x][y][i] - mean[i])**2 }**0.5
w*h x=0 y=0
where, in the case of mean == NULL,
1 w-1 h-1
mean[i] = ----- * SUM SUM img[x][y][i]
w*h x=0 y=0
PARAMETERS
The function takes the following arguments:
sdev Pointer to standard deviation array, whose size is the number of channels in the source image. sdev[i] contains the stan-
dard deviation of channel i.
img Pointer to input image.
mean Pointer to pre-computed mean array for each channel. (If NULL, it will be computed.) mean[i] contains the mean of channel
i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
