Hello, motoxeryz125:

You say you've tried a few commands but they failed with errors. It would be helpful to see the commands/code and the errors.

When you say that you're missing libraries, do you mean that the sed executable is missing libraries that it requires to work at all? If so, before the file processing can be done, you need to first install unix tools that work (cygwin perhaps?) or use a windows native alternative. For the latter, you may have Powershell available. If not, it should be a simple download and double-click to install. There's also the command.exe batch language and the windows/dos utilities, but I am not at all familiar with how/if they would work for this case.

Regards and welcome to the forum,
Alister

gc

GC(1)                                                         General Commands Manual                                                        GC(1)

NAME

       gc - count graph components

SYNOPSIS

       gc [ -necCaDUrs?  ] [ files ]

DESCRIPTION

       gc is a graph analogue to wc in that it prints to standard output the number of nodes, edges, connected components or clusters contained in
       the input files.  It also prints a total count for all graphs if more than one graph is given.

OPTIONS

       The following options are supported:

       -n     Count nodes.

       -e     Count edges.

       -c     Count connected components.

       -C     Count clusters. By definition, a cluster is a graph or subgraph whose name begins with "cluster".

       -a     Count all. Equivalent to -encC

       -r     Recursively analyze subgraphs.

       -s     Print no output. Only exit value is important.

       -D     Only analyze directed graphs.

       -U     Only analyze undirected graphs.

       -?     Print usage information.

       By default, gc returns the number of nodes and edges.

OPERANDS

       The following operand is supported:

       files   Names of files containing 1 or more graphs in dot format.  If no files operand is specified, the standard input will be used.

EXIT STATUS

       The following exit values are returned:

       0   Successful completion.

       1   The -U or -E option was used, and a graph of the wrong type was encountered.
