Hello,
I have a strange problem with grep. When I try to search for a string in the files of a directory (~/programming/tmp) with the command
grep a *
it gives me the error:
grep: conflicting matchers specified
If I do (from my home directory or even from the directory itself!)
grep a ~/programming/tmp/*
then I have no problem. What is the meaning of the above error message? It does not matter what string I give, anything will produce the error.

Do you have any of GREP_OPTIONS or POSIXLY_CORRECT set?
That error generally means that egrep was called with the -F or -G flag or fgrep was called with the -E or -G flag. Basically, the matchers (grep/fgrep/egrep) conflict with each other.
I think you can't use egrep with POSIXLY_CORRECT or something like that.

That error generally means that egrep was called with the -F or -G flag or fgrep was called with the -E or -G flag. Basically, the matchers
I solved the problem. There was a file called -FILE in that directory.

Ok. grep took that to mean flags -F -I -L and -E. Basically, -F and -E together not allowed. You can solve the problem by putting -- before the pattern to tell grep that options are over, or alternately, put the pattern in quotes, and set POSIXLY_CORRECT, which will assume that everything after the pattern is a filename.

Thanks a lot Navin, but I am looking for RH6.2 only. Any helps. --Sandeep

I don't think there is such a thing. Try scp'ing the file, if that fails you can mail.
perhaps "tcl/expect" is the answer to the question. it is supposed to do exactly this kind of stuff... for more details look at www.tcltk.org pradeep

Try expect. it is designed to be used with the interactive programms. it will solve your problem.
When sending emails, I have set my Linux Box to represent as "aaaaaa.com", which is a non existing domain. Now if I send an email from this linux box [aaaaaa.com domian] to some yahoo.com address which does not exist, say bbbbb@yahoo.com, then the Yahoo SMTP will bounce this mail back. The Yahoo SMTP will bouce the mail back to the SMTP of aaaaaa.com [ which does not exist ]. So what will happen to the bounce back mail. WHat will yahoo's SMTP do.throw it in >>NULL, or what.
If I understand the SMTP / TCPIP correctly then this mail will be bounced back to my linux box then & there. But what if my linux box gives it to the yahoo SMPT which has along que, and I disconnect my Linux box from the internet.
I hope I have been able to exlpain my query. Just getting some fundas cleared.
ANy comments. --Sandeep

I'm assuming that yahoo blocks non-existent domains from sending mail.
It depends on how the mail is being sent. If your smtp server connects directly to yahoo's smtp server then the mail will be rejected before it even leaves your machine. Not because the destination account does not exist, but because the source domain does not exist.
If you send your mail through a smart host, then it depends on how your smart host is configured. If it is configured to block non-existent domains, then same problem. If non-existent domains are allowed to connect, then the mail will go to your smart host, but will be rejected from yahoo.
Now, assuming that the mail has in fact managed to get out of your system, and got somewhere - either your smart host, or yahoo. It will bounce for one of the two reasons. Where does it bounce to?
The server that is bouncing the mail will basically do a MX lookup for the destination domain (aaaaa.com), but will not find it. It will realise that it cannot return the mail, so will check what it is configured to do in such cases. In most cases, it would be configured to bounce the mail to a postmaster in its own domain, and this it what it does.
Does that answer your question?
Philip
Hi Philip, I used YAHOO as just an example, it could be any SMTP, VSNL, HOTMAIl etc. But ur last part did anser my question. The recving SMTP will do a MX lookup and upon not able to find the respectibve IP it will dump it to the local SMTP postmaster. Thanks. --Sandeep
