Actually Vim is a powerful editor there are a lot of plugins available even we can maintain a todo list in vim taskpaper is used to do that.

In some previous days i used Vim to open,read,write simple purpose just recent days only i started to use for search,copy for those purposes too
There are a lot of editors available command line utility is the good for programmers like technician
Vim(old) is gold

:  To enter into vim command mode

vim commands only has to be entered in this mode only,so when ever we need to do enter vim commands we should use this colon character
:e file_name To open a file [Eg: :e post.txt]
:tabnew To open new tab
:tabfirst[tablast] Switch to first tab ,last tab respectively
:sav or :w used to save the files
Replace a string in a file

:%s/old_string/new_string/g here the string replacement occurs in all lines of the file

if you want to do this operation in a particular set of lines

:3,$s/old_string/new_string/g Starting line no 3 to End OF file
:%s/^/start/g Add the String “Start” in all starting lines of your file
:%s/$/end/g Add the String “end” in all ending lines of your file

:g/string/d Delete all lines what has the string
:v/string/d Delete all lines what hasn’t contain the string

:2,45 w another_file.txt // Witre the lines from 2 to 45 to another file
:2,45 w >> another_file.txt //To append those lines to another file

Ctrl+n Ctrl+p (in insert mode)

Complete wordCtrl+x Ctrl+l

Complete line:set dictionary=dict Define dict as a dictionnary

Ctrl+x Ctrl+k Complete with dictionnary

set shiftwidth=3 //for indentation space

set autoindent //auto indent

Would you want to change the Case in all lines of your file
Execute this command in your vim mode
:for i in range(0,line(‘$’))

[“indent need”]call setline(i,tolower(getline(i)))


Get the No of lines in for loop and call the function setline to set all lines as lowercase similar that we can peroform for toupper(),..
If you want to change the cases in line only
Press ‘V‘(caps)
and press ‘e‘ then press ‘u‘  for small case
press ‘E‘ then press ‘U” for big case

Do in All tabs:

If you want to do your vim commands in all opened tabs means you can use the command tabdo
:tabdo %s/old_string/new_string/g

okay these are the commands which i learnt recenly 😉 I hope this will be useful for you in some way
okay if you find any problem with this means send me for a discussion
