Given a -Ffunction option, DeleGate runs to do the specified function which typically is a client-side action of a certain protocol. You can omit entering lengthy "delegated -F" by giving a file name "function" to an DeleGate executable file and just call it as function. The matching of function name is case-insensitive.

Command line options before -Ffunction and after "--" option is regarded as options for DeleGate rather than for the function, as delegated dgopt ... dgopt -Ffunc fopt ... fopt -- dgopt ... dgopt. As an exception, parameter option, in name=value format, is recognized as a parameter for DeleGate even if it appeared at fopt position.

Example: using DeleGate as a resolver

% delegated -Fresolvy www.delegate.org
% ln -s delegated Resolvy
% Resolvy www.delegate.org

The following is a list of major functions.

-Fhelp

put a list of available functions

-Fkill[-hup] -Pport

terminate (or restart) the DeleGate sending SIGTERM (or SIGHUP)

-Fimp

implant configuration parameters into the executable file

-Fcgi [DeleGateOptions]

run as a CGI program of an arbitrary HTTP server

-Fconnect host port[/udp] [XCOM=clientCommand]

like a telnet client, connect to the specified host:port and relay the standard I/O to/from it.

-Fresolvy {[-MX.]hostname | IPaddress[-num]}

like nslookup(8), resolve a given host name or IP address (can be a range as 10.10.10.1-128)

-Ffindu [-atime N] [-ls] [-du] [-rm] ... [dir]*

like find(1), find a file to apply a specified action. Usage will be shown by "delegated -Ffindu".
Example: doing "find . -ls" together with "du(1)"

delegated -Ffindu -ls -du

-Fdget [-h] [-o] [-eencoding] [PROXY=host:port] [MYAUTH=user:pass] URL

download a resource specified by URL, and put to standard output with "-o" option. With "-h" option, the header part of a HTTP response message will be put together.

-Ficp [-h server] URL

work as an ICP client. Usage will be shown by "delegated -Ficp".

-Fsched {"crontabSpec" | crontabFile | schedSpec}*

like cron(8), cause specified actions at specified timing.
Example: cause an action every 15 minutes

delegated -Fsched "0,15,30,45 * * * * /bin/date"

schedSpec is the canonical format of scheduling specification.

schedSpec == Wday:year:month:mday:Hour:Min:Sec:action

Example: cause an action every 15 seconds

delegated -Fsched "*:*:*:*:*:*:0,15,30,45:/bin/date"

-Fmd5 [infile]

output the MD5 digest of input data

-Fauth -{a|d|v} username[:password] hostname[:portnumber] [expire]

Add, delete or view predefined (or cached) authorization information for hostname as a server for AUTHORIZER. If hostname is prefixed with "-", it is regarded as a virtual name without a real server.
Example:

delegated -Fauth -a ken:blahblah -smtp.users.local
// and refer this as AUTHORIZER=-smtp.users.local
