for compiled executables, try src(1).

in this particular case, however, the services are implemented by shell scripts.
see listen(8) for details, but they are found in /rc/bin/service and /rc/bin/service.auth,
in files named using an obvious naming scheme (eg, /rc/bin/service/tcp7).

	term% cat /bin/service/tcp7
	#!/bin/rc
	/bin/cat

so much for that one.  others such as tcp25 invoke specialised commands
with appropriate argument shuffling:

	term% cat /bin/service/tcp25
	#!/bin/rc
	#smtp serv net incalldir user

	user=`{cat /dev/user}
	exec upas/smtpd -n $3

and then you can do
	src /bin/upas/smtpd
to pop the source of the command into an acme frame, or use
src -n just to print the name:

	term% src -n /bin/upas/smtpd
	/sys/src/cmd/upas/smtp/smtpd.c:71

Is there a way to find (discover the path) of a file
in the source tree? For example, source for echo server
running on port 7 (if the name is echo.c??).

i ought to have added that although i used absolute names to
make it clearer which file src was examining, i could have said
	src upas/smtpd
or
	src smtpd
and let it hunt for it in /bin and /bin/* itself.

it actually works for scripts as well, thus
	src tcp7
	src tcp25
would track down the services (but you'd have had to know the naming scheme).

try
	src src

One might normally use the src(1) command,
however,

	src echo

finds the source to the echo(1) command.

	cat /rc/bin/service/tcp7

shows the real command for tcp echo. It its cat(1).
