Get yourself som new themes for vim

Well, you would already have some themes for your vim, by default. And if you did not like them then you would have added some of your own too (downloaded from vim.org). But, those are something, that you might not still like and want to make some changes.

Here’s, a new way to do it. Just go to the link mentioned below and click on Generate Dark or Generate Light. You can generate as many as you like and once you like the theme, simply click on vim in the bottom and download 🙂 BTW, you can generate textmate and Emacs theme as well.

Using file partially for filenames

There are some commands that take file name and there are some case where you need to give file name. But there are some cases where you want to modify the file before passing it to the command. What do you do in these case’s?

I had a file containing huge amount of data and for some testing I wanted to pass only the first few lines of the file and not the complete file.  And since the file only accepted filename and would not take any input from the STDIN so only option was to create a file with the required data in a temporary file. So, I sat back to figure out some way to do it and finally found I can use this:

testcommand -f<(head -1 )

The “testcommand” parameter “-f” requires a filename. And here we are passing the file to the command after filtering it with head command. You can use any bash command inside the <() combination.
