I have a huge log file (25.3 million lines) with errors and I won’t to search it without holding down the up button. How can you search this with vi? I’ve seen similar at directory levels but not particular files. At the moment I’ve searched a date e.g. /Tue 15 Jan
and navigated down but I’m not sure when problems may have began (only when noticed) so I need a general search.

My general idea from within the file would be /ORA-/!ORA-00020
meaning that I want to find those strings containing “ORA-” but ignoring those that are “ORA-00020”. Any idea how this can be done viewing a particular file?

Thanks for any info

    You do 

     grep -v "ORA\-00020" error.log > error2.log

    then you search error2.log
