I am trying to display line that doesn't contain string1 or string2 or ...
stringn.
What I did was
grep -v string1 | grep -v string2 | .... | grep -v stringn
Just wondering if there is an easier way other than doing all this piping.
Thanks in advance.

egrep -v 'string1|string2|string3|...|stringN' file
or put them in a file and use
fgrep -vf badstrings file
Bear in mind that most standard fgrep's are terribly slow.
