— otherwise .. <div class="zemanta-pixie"><img class="zemanta-pixie-img" src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/pixy4.gif" />
Here I will take an example of rss2email list, but I guess I will be able to pass on the concept.
Here is example of the output of the r2e list command:

4: http://blogs.members.freewebs.com/Members/Blogs/viewBlogRSS.jsp?userid=29731143 (default: amitag@localhost)
Target here is to get the list of all duplicate entries if any. So, first we need to remove the numbers from the begining and the email ID from the end.
Continue readingLot of times I end up changing a particular text in config file to some other text. And when I have to do it for multiple files, all files having the text in multiple places, I end up opening the files in vim and then doing a globlal replace. But this is not efficient so I cam up with some one liners to do this for me. For removing any occurance of text in all files in the directory :

Today I was just wondering how good it would be to have a script to change the <a class="zem_slink freebase/en/vim" title="Vim (text editor)" rel="homepage" href="http://www.vim.org/">vim colorscheme from the <a class="zem_slink freebase/en/cmd_exe" title="Command Prompt" rel="wikipedia" href="http://en.wikipedia.org/wiki/Command_Prompt">command prompt. The plan for the script was simply to print the list of available schemes and then let the user select the actions from there on. So, here is the result:

The script also gets the <a class="zem_slink freebase/en/universally_unique_identifier" title="Universally Unique Identifier" rel="wikipedia" href="http://en.wikipedia.org/wiki/Universally_Unique_Identifier">UUID and uses the same to make the entry 🙂

This is one of my favourites, alwahs keep it handy. Linux is case sensitive by nature but you will always find filenames jumbled up in the case. So what is the solution:
bind ”set completion-ignore-case on”
Just execute the above in your bash command and file/dir name will behave like Windows. Remember that this is per session setting and thus the names do not get changed internally, it only changes the way to access it (specifically completion only). So if you want this behaviour in all your sessions put this in the appropriate profile file.
