In (any) vi, add a keystroke to format the current paragraph.

2010-04-11 1 min read Linux

<a id="aptureLink_F2g9MXMw3t" href="http://en.wikipedia.org/wiki/Vi">vi editor is very powerful in the sense that you can use maps, abbreviations and recordings. One such example is when you are trying to write a email or trying to write a paragraph and you want to format it. You can create a mapping like so, in your .exrc or .vimrc and use it to format the paragraph.

Script to get the number of events from the logs.

2010-04-11 2 min read Learning Linux Perl

I was trying to do some <a class="zem_slink freebase/en/log_analysis" title="Log analysis" rel="wikipedia" href="http://en.wikipedia.org/wiki/Log_analysis">log analysis and finding the events in the logs. For this the logs had the Events logged as ”|+Event name|” or with sending and receiving. So I wrote this little script to take care of my requirements.

vim understanding the various modes and using the yanking more efficiently.

We will look at the vim modes today. Sometime back , I was looking at copying a function body. So I was basically looking to copy the lines till matching ”}”. I found a plugin called <a href="http://www.vim.org/scripts/script.php?script_id=1234" target="_blank">yankring which would allow me to yank the text in various combinations. So I can copy a function by going to the begining of the function and then ”y}”. That is very simple to understand right? Wrong!!!

vim search multiple files

2010-03-25 1 min read Linux Vim Tips

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 🙂
