sig2dot [Options] < input-file > output-file
This manual page documents briefly the sig2dot command. Sig2dot parses the output of "gpg --list-sigs" and produces a .dot file that can be used as input to a graphing program.
sig2dot accepts the following options:
Black and white / do not colorize.
- -d <date>
Render graph as it appeared on <date> (ignores more recent signatures). Date must be in the format "YYYY-MM-DD". Will also ignore keys that have since been revoked.
- -s <html-file-name>
Produces a sory HTML statistics file with the number of signatures per node.
Graph all keys, even if they do not have a signature
- -r <key-revoked-string>
Sets the text for the key-revoked string used by GnuPG. The default is what is used in the English version. This parameter can be set for versions of GnuPG localized to other languages. Default: "[revoked".
- -t <title>
Sets the title for the graph generated. Default: "Keyring Statistics".
- -u <user-not-found-string>
Sets the text for the user-not-found string used by GnuPG. The default is what is used in the English version. This parameter can be set for versions of GnuPG localized to other languages. Default: "[user id not found]".
Print help and exit.
Print version and exit.
