watchgnupg - Read and print logs from a socket
watchgnupg [--force] [--verbose] socketname
Most of the main utilities are able to write their log files to a Unix
Domain socket if configured that way. watchgnupg is a simple listener
for such a socket. It ameliorates the output with a time stamp and
makes sure that long lines are not interspersed with log output from
other utilities. This tool is not available for Windows.
watchgnupg is commonly invoked as
which is a shorthand for
watchgnupg --force $(gpgconf --list-dirs socketdir)/S.log
To watch GnuPG running with a different home directory, use
watchgnupg --homedir DIR
watchgnupg understands these options:
Delete an already existing socket file. This option is
implicitly used if no socket name has been given on the command
If no socket name is given on the command line, pass DIR to
gpgconf so that the socket for a GnuPG running with DIR has its
home directory is used. Note that the environment variable
GNUPGHOME is ignored by watchgnupg.
Instead of reading from a local socket, listen for connects on
TCP port n. A Unix domain socket can optionally also be given
as a second source. This option does not use a default socket
Do not print the date part of the timestamp.
Enable extra informational output.
Print version of the program and exit.
--help Display a brief help page and exit.
$ watchgnupg --time-only
This waits for connections on the local socket (e.g.
`/var/run/user/1234/gnupg/S.log') and shows all log entries. To make
this work the option log-file needs to be used with all modules which
logs are to be shown. The suggested entry for the configuration files
If the default socket as given above and returned by "echo $(gpgconf
--list-dirs socketdir)/S.log" is not desired an arbitrary socket name
can be specified, for example `socket:///home/foo/bar/mysocket'. For
debugging purposes it is also possible to do remote logging. Take care
if you use this feature because the information is send in the clear
over the network. Use this syntax in the conf files:
You may use any port and not just 4711 as shown above; only IP
addresses are supported (v4 and v6) and no host names. You need to
start watchgnupg with the tcp option. Note that under Windows the
registry entry HKCU\Software\GNU\GnuPG:DefaultLogFile can be used to
change the default log output from stderr to whatever is given by that
entry. However the only useful entry is a TCP name for remote
gpg(1), gpgsm(1), gpg-agent(1), scdaemon(1)
The full documentation for this tool is maintained as a Texinfo manual.
If GnuPG and the info program are properly installed at your site, the
should give you access to the complete manual including a menu
structure and an index.
