Hi,
Im reading an ANSI text file and greping for a pattern. Then i cut what i dont need from that pattern. So now i just have what i need. What i have now just so happens to be a constant integer. How can i save this integer in a varaible? Or do i use command capture in some form?
cat... (2 Replies)
Is there any setting required to define upper cap for a user to restrict the file transmission?
If yes, what it is & can non-admin user be able to revoke that? (0 Replies)

gcv - graph file converter
SYNOPSIS
gcv [options] [igfile] [ogfile] [oxfile]
DESCRIPTION
The gcv program converts Scotch graph files from and to other external file formats.
File igfile is converted into graph file ogfile, with optional geometry data being put in geometry file oxfile, if it is available.
When file names are not specified, data is read from standard input and written to standard output. Standard streams can also be explicitly
represented by a dash '-'.
When the proper libraries have been included at compile time, gcv can directly handle compressed graphs, both as input and output. A stream
is treated as compressed whenever its name is postfixed with a compressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The compres-
sion formats which can be supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma', on input only).
OPTIONS -h Display some help.
-iifmt Set format of input graph file, which can be:
bnum Boeing-Harwell format. This is a matrix format. Only square matrices are supported. Square matrices with unsymmetric pattern
are symmetrized. In case the file contains several matrices, the num parameter allow the user to provide the index of the
matrix to convert, starting from 0. When the num parameter is not set, it is assumed to be 0.
c Chaco format. This is an adjacency graph format, also used by MeTiS.
m Matrix Market format. This is a matrix format describing individual edges. Matrix pattern is symmetrized, such that rectangu-
lar matrices are eventually squared.
s Scotch graph format. This is an adjacency graph format.
-oofmt Set format of output graph file, which can be:
c Chaco format.
m Matrix Market symmetric pattern format.
s Scotch format. This is the default.
-V Display program version and copyright.
EXAMPLE
Convert a Matrix Market graph into a Scotch graph. Matrix Market files do not comprise geometry data, so no geometry file is needed on out-
put:
$ gcv -im brol.mm brol.grf
