remove Ctrl-M characters in unix

a file edited using windows format might have ^M at the end of each line.
This would be annoying when it comes to the unix world.
Two easy ways to remove this -
1. dos2unix command

2. Vim search & replace

:%s/^V^M//g [ type Ctrl-V Ctrl-M]


this will translate to


:%s/^M//g [ remember Ctrl-V is escape sequence in Unix]


now bangalore autowallas can speak about 'IT'

recently i was travelling to cantonment railway station taking an auto from thipasandra. Initially
i was surprised when the autowalla talked to me in english. He started asking where I work for, my onsite experience and all the IT related stuffs. he even asked me about the technology that I
work on. When i said that i work in software, he asked Java or .NET!!! huhh!!!. He even asked me about Obama's IT policy and asked if that would have any impact on IT in bangalore. oh man, how come you know all these facts?!!! He know that IT in bangalore is their bread and butter for the autowallas. wowww people are raising ahead by trying to learn something.. good..

tabs in vim

Sometimes it would useful to view the files as tabs(IMV, may be, just may be only when you
want to know what files are open without doing :files in vim command prompt. ). Here is
the solution for it.

here is the gist of the feature.

1. You could invoke it either with -p command switch option or :tabnew command option.
2. use 'gt' to switch between the tabs.
3. Use ':tabdo blah' to run a command over all the tabs ( eg. search and replace)

its cool
