I have a 6 GB text file. It has an access record for a whole month to my website.
That file is my only hope to know how a someone got access to my website and hacked it.
But, as the file is too big, gedit doesn't open it.

Is there any command or method I could use to read or search in the content of that file?

I tried the following command grep -i '18/jan' 02records but it takes a while and then no results show. I want lines that have '18/jan'.

Thanks
