convert format and select subset
SYNOPSIS
copyg
[,-gszfp#:#qhx/] [,infile /[,outfile/]]
DESCRIPTION
-
Copy a file of graphs with possible format conversion.
- -g
-
Use graph6 format for output
- -s
-
Use sparse6 format for output
- -z
-
Use digraph6 format for output
- -i
-
Use incremental sparse6 format for output
-
In the absence of -g, -s, -z or -i, the format
depends on the header or, if none, the first input line.
As an exception, digraphs are always written in digraph6.
-
-p# -p#:#
-
- Specify range of input lines (first is 1)
This can fail if the input has incremental lines.
-f With -p, assume input lines of fixed length
-
(ignored if header or first line has sparse6 format).
-
-I# Have at most this number of incremental steps
- in a row.
-
Implies -i.
- -h
-
Write a header.
- -x
-
Don't write a header.
-
In the absence of -h and -x, a header is written if
there is one in the input.
- -q
-
Suppress auxiliary output.
