Sorry to ask here -it´s just that I know someone here can fix me up (shameless grovel!!).
I´m in a bit of a bind, trying to recover a corrupt file for a client. The first issue is that the file is 1.8gig, so I´m wondering if I´m going to have problems with cat <file>|grep <regex> >outputfile.txt....
Do you need the cat?
Someone please tell me if I'm wrong, but shouldn't this work:
grep <regex> <file> > outputfile.txt
One less action to get in the way.
or is there a text editor which could handle that size (I have 512-meg RAM, and I know some editors try to load the whole thing into memory first)
Then the real crunch:
The following is the expression which is given on a website to do exactly what I need:
[^\received: from .*\r
and the second,
[^\t].*\rReceived: from .*\r
....but they both appear to have syntax errors!!!
What are the exact strings that you are looking for? It may be a little bit easier to determine what characters you need in your search pattern if we knew that.
Can anyone help fix these up please - it´s rather urgent.
Thanks a lot
john
