i'm not sure if i know what you mean
1. rute tutorial looks very good ;-) thx
2. the tutorial i search (the advanced bash scripting tutorial) explained io redirection (and it didn't work)
--> i thought there was an failure in the tutorial
so, why shouldn't the bash tutorial have anything to do with my topic?
3. i tried some example on a suse distri (very new, don't know exactly the version)
i tried: cat * | grep "nothingfound" >> test.out 2>&1
bash did it, but there was nothing in test.out and cat throwed a few error messages (because it tried to cat a directory, which is what i wanted, because of the 2>&1 redirection ;-))
BUT: cat * >> test.out 2>&1 | grep "nothingfound"
works (i know it's not very usefull example)
i understand why, but it looks now as if 2>&1 works also using linux??
i thought it should "only" work on OS/2
if the above example works why doesn't work this:
./anyprogram >> test.out 2>&1
anyprogram is a self written prog (C++), which uses system command to execute some scripts, which could make error messages
but if i cat test.out there is no Error message?
is io redirection really as that complicated as it looks like (for me )
