Full Discussion: redirect to both file and std output at the same time
Top Forums UNIX for Advanced & Expert Users redirect to both file and std output at the same time Post 302239482 by Gee-Money on Tuesday 23rd of September 2008 09:30:13 PM

I'm not sure which unix you are using, but if you have the 'tee' command installed, you can use that.

Code:
# echo hello | tee outfile
hello

Code:
# cat outfile
hello

you can use the -a option to just append to the file

Code:
# echo world | tee -a outfile

and now you have

Code:
# cat outfile
hello
world

If you dont have tee, and cant install it, then you are probably looking at some crazy file descriptor re-assignment/redirection, of which i'm not entirely keen.

std::basic_ostream_sentry

std::basic_ostream< _CharT, _Traits >::sentry(3cxx)					       std::basic_ostream< _CharT, _Traits >::sentry(3cxx)

NAME

       std::basic_ostream< _CharT, _Traits >::sentry -

SYNOPSIS

   Public Member Functions
       sentry (basic_ostream< _CharT, _Traits > &__os)
       ~sentry ()
       operator bool () const

Detailed Description
   template<typename _CharT, typename _Traits>class std::basic_ostream< _CharT, _Traits >::sentry
       Performs setup work for output streams.

       Objects of this class are created before all of the standard inserters are run. It is responsible for exception-safe prefix and suffix
       operations.

       Definition at line 379 of file ostream.

Constructor &; Destructor Documentation
   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::sentry (basic_ostream< _CharT, _Traits > &__os)
       [explicit]
       The constructor performs preparatory work. Parameters:
	   os The output stream to guard.

       If the stream state is good (os.good() is true), then if the stream is tied to another output stream, is.tie()->flush() is called to
       synchronize the output sequences.

       If the stream state is still good, then the sentry state becomes true (okay).

       Definition at line 49 of file ostream.tcc.

       References std::ios_base::failbit, std::basic_ios< _CharT, _Traits >::good(), std::basic_ios< _CharT, _Traits >::setstate(), and
       std::basic_ios< _CharT, _Traits >::tie().

   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::~sentry () [inline]
       Possibly flushes the stream. If ios_base::unitbuf is set in os.flags(), and std::uncaught_exception() is true, the sentry destructor calls
       flush() on the output stream.

       Definition at line 407 of file ostream.

       References std::ios_base::badbit, std::uncaught_exception(), and std::ios_base::unitbuf.

Member Function Documentation
   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::operator bool () const [inline],	[explicit]
       Quick status checking. Returns:
	   The sentry state.

       For ease of use, sentries may be converted to booleans. The return value is that of the sentry state (true == okay).

       Definition at line 428 of file ostream.
