vim search multiple files

Searching some pattern in multiple files is something that is required very often. There are multiple ways to do it, like <a class="zem_slink freebase/en/grep" title="Grep" rel="wikipedia" href="http://en.wikipedia.org/wiki/Grep">grep, <a class="zem_slink freebase/guid/9202a8c04000641f8000000006b66ec6" title="Ack (command-line utility)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Ack_%28command-line_utility%29">ack, find and so on so forth. But if your editor already has the capability to do that, then why leave your favourite vi and go to shell. I will point you to some scripts and some wiki pages on how to do this 🙂

Color in grep output to distinquish the matching entries

Most of the times I end up spending a lot of time to look for the string in the grep output when I do a search. This is quite frustrating and thus I looked at the options for grep command that would make my life easier and there definately is something. Here it is:

export GREP_COLOR=&#8221;5;36&#8221;

But for this to work you would still need to give the &#8221;–color=auto&#8221; option in the grep command. There are two ways to do this, create a alias for grep as &#8221;grep –color=auto&#8221; or specify the same in GREPOPTIONS.

grep -v with multiple patterns.

$ sed '/test/{/error|critical|warning/d}' somefile If you wanted to do all in one command, you could go w/ sed instead
