I found the expression: .+LOG.+
You're still making it too complicated for programs such as ed, vi, grep, egrep or sed, patterns are not required to match the whole line. That means the ".+" parts are redundant. If you really want to exclude from treatment those lines where "LOG" occurs at the beginning or end, then use the pattern ".LOG." (sans quotes, of course).
That means 'one arbitrary character' "LOG" 'one arbitrary character', which is something else.
Under some circumstances regular expression efficiency matters little, but given the size to which log files can grow, more efficient regular expressions are worth using.
So here's what you want to do:
% sed -e '/LOG/d' originalLogFile >filteredLogFile
fgrep -v 'LOG' originalLogFile >filteredLogFile
If you really want to exclude those lines where LOG occurs at the beginning or end, then use this:
% sed -e '/.LOG./d' originalLogFile >filteredLogFile
fgrep -v '^LOG\|LOG$' originalLogFile >filteredLogFile -dnh -- Fertility is hereditary. If your parents didn't have any children, neither will you. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
