       gpg-connect-agent - Communicate with a running agent

       gpg-connect-agent [options][commands]

       The gpg-connect-agent is a utility to communicate with a running gpg-agent.  It is useful to check out the com-
       mands gpg-agent provides using the Assuan interface.  It might also be useful  for  scripting  simple  applica-
       tions.  Input is expected at stdin and out put gets printed to stdout.

       It is very similar to running gpg-agent in server mode; but here we connect to a running instance.

       The following options may be used:


              Output additional information while running.


              Try to be as quiet as possible.

       --homedir dir
              Set  the  name  of the home directory to dir. If this option is not used, the home directory defaults to
              '~/.gnupg'.  It is only recognized when given on the command line.  It also overrides any home directory
              stated  through  the environment variable 'GNUPGHOME' or (on W32 systems) by means of the Registry entry


       --raw-socket name
              Connect to socket name assuming this is an Assuan style server.  Do not run any special  initializations
              or environment checks.  This may be used to directly connect to any Assuan style socket server.


       --exec Take  the  rest  of the command line as a program and it's arguments and execute it as an assuan server.
              Here is how you would run gpgsm:
          gpg-connect-agent --exec gpgsm --server
       Note that you may not use options on the command line in this case.

              When using -S or --exec, gpg-connect-agent connects to the assuan  server  in  extended  mode  to  allow
              descriptor passing.  This option makes it use the old mode.

       --run file
              Run  the commands from file at startup and then continue with the regular input method.  Note, that com-
              mands given on the command line are executed after this file.


              Run the command /subst at startup.

       --hex  Print data lines in a hex format and the ASCII representation of non-control characters.

              Decode data lines.  That is to remove percent escapes but make sure that a new line always starts with a
              D and a space.

       While  reading  Assuan  commands, gpg-agent also allows a few special commands to control its operation.  These
       control commands all start with a slash (/).

       /echo args
              Just print args.

       /let name value
              Set the variable name to value.  Variables are only substituted on the input  if  the  /subst  has  been
              used.  Variables are referenced by prefixing the name with a dollar sign and optionally include the name
              in curly braces.  The rules for a valid name are identically to those  of  the  standard  bourne  shell.
              This  is  not yet enforced but may be in the future.  When used with curly braces no leading or trailing
              white space is allowed.

              If a variable is not found, it is searched in the environment and if found copied to the table of  vari-

              Variable  functions  are  available: The name of the function must be followed by at least one space and
              the at least one argument.  The following functions are available:

              get    Return a value described by the argument.  Available arguments are:

                      cwd    The current working directory.

                             The gnupg homedir.

                             GnuPG's system configuration directory.

                      bindir GnuPG's binary directory.

                      libdir GnuPG's library directory.

                             GnuPG's library directory for executable files.

                             GnuPG's data directory.

                             The PID of the current server. Command /serverpid must have been given to return a useful

              unescape args
                     Remove  C-style  escapes  from args.  Note that \0 and \x00 terminate the returned string implic-
                     itly.  The string to be converted are the entire arguments right behind the delimiting  space  of
                     the function name.

              unpercent args

              unpercent+ args
                     Remove  percent  style  escaping from args.  Note that %00 terminates the string implicitly.  The
                     string to be converted are the entire arguments right behind the delimiting space of the function
                     name. unpercent+ also maps plus signs to a spaces.

              percent args

              percent+ args
                     Escape  the  args using percent style escaping.  Tabs, formfeeds, linefeeds, carriage returns and
                     colons are escaped. percent+ also maps spaces to plus signs.

              errcode arg

              errsource arg

              errstring arg
                     Assume arg is an integer and evaluate it using strtol.  Return the gpg-error  error  code,  error
                     source or a formatted string with the error code and error source.





              %      Evaluate all arguments as long integers using strtol and apply this operator.  A division by zero
                     yields an empty string.



              &      Evaluate all arguments as long integers using strtol and apply the logical oeprators NOT,  OR  or
                     AND.  The NOT operator works on the last argument only.

       /definq name var
              Use  content  of  the  variable  var  for inquiries with name.  name may be an asterisk (*) to match any

       /definqfile name file
              Use content of file for inquiries with name.  name may be an asterisk (*) to match any inquiry.

       /definqprog name prog
              Run prog for inquiries matching name and pass the entire line to it as command line arguments.

       /datafile name
              Write all data lines from the server to the file name.  The file is opened for writing and created if it
              does not exists.  An existing file is first truncated to 0.  The data written to the file fully decoded.
              Using a single dash for name writes to stdout.  The file is kept open until a new file is set using this
              command or this command is used without an argument.

              Print all definitions

              Delete all definitions

       /sendfd file mode
              Open  file  in  mode  (which  needs to be a valid fopen mode string) and send the file descriptor to the
              server.  This is usually followed by a command like INPUT FD to set the input source for other commands.

              Not yet implemented.

       /open var file [mode]
              Open file and assign the file descriptor to var.  Warning: This command is experimental and might change
              in future versions.

       /close fd
              Close the file descriptor fd.  Warning: This command is experimental and might  change  in  future  ver-

              Show a list of open files.

              Send the Assuan command GETINFO pid to the server and store the returned PID for internal purposes.

       /sleep Sleep for a second.


       /nohex Same as the command line option --hex.


              Same as the command line option --decode.


              Enable  and  disable  variable  substitution.   It  defaults  to disabled unless the command line option
              --subst has been used.  If /subst as been enabled once, leading whitespace is removed from  input  lines
              which makes scripts easier to read.

       /while condition

       /end   These commands provide a way for executing loops.  All lines between the while and the corresponding end
              are executed as long as the evaluation of condition yields a non-zero value.  The evaluation is done  by
              passing condition to the strtol function.  Example:

           /let i 3
           /while $i
             /echo loop couter is $i
             /let i ${- $i 1}

       /run file
              Run commands from file.

       /bye   Terminate the connection and the program

       /help  Print a list of available control commands.
