Hello,
Decided to edit the whole post as nobody was replying, and it was pretty darn big as it was. So I have to write this script for my assignment, and I am new to scripting. The problem is we have to handle command line args, process an operations file which adds supermarket items to a database... (7 Replies)

mm2gv - Matrix Market-DOT converters
SYNOPSIS
mm2gv [ -cluv? ] [ -ooutfile ] [ file ]
DESCRIPTION
mm2gv converts a sparse matrix of the Matrix Market format to a graph in the GV (formerly DOT) format.
OPTIONS
The following options are supported:
-c This flag causes mm2gv to assign colors to the edges. The matrix element is scaled to the range [0,1] depending on where it lies
between the minimum and maximum set matrix values. This scaled value is used as the "wt" attribute of the corresponding edge. In
addition, this scalar value is mapped to an RGB value, which is stored as the edge "color".
-l If set, mm2gv attaches a label to the graph indicating the base name of the input file, and the number of nodes and edges.
-u If specified, the graph is assumed to be undirected. By default, the graph generated is directed.
-v This flag causes mm2gv to store the matrix values as the "len" attribute of the corresponding edge.
-ooutfile
Prints output to the file outfile. If not given, mm2gv uses stdout.
OPERANDS
The following operand is supported:
file Name of the file in MatrixMarket format. If no file operand is specified, the standard input will be used.
RETURN CODES
Return 0 if there were no problems during conversion; and non-zero if any error occurred.
