Delete and redirect lines in Vim to another file

阅读更多关于 Delete and redirect lines in Vim to another file

问题 I want to delete say last 10 lines and move it to another file. What I currently do is: select last 10 lines in visual mode, write these lines by :'<,'>w to other file, and then delete selected lines. Is there any more efficient way I can do this? 回答1: You can use ex commands instead. e.g. :1,10w file.name Write the first ten lines :$-9,$w file.name Write the last ten lines (the dollar sign denotes last line) With the code below in your .vimrc you can use the command :MoveTo file.name

问题 I am trying to remove words from a line if they contain a specific string. Here is an example of the text: host-a, host-b, host-c+test, host-d, host-e+test I want to remove anything that contains +test , to result with: host-a, host-b, host-d Likewise, I need to apply this on a line by line basis, not on all lines in the file. It is going to be used within a macro. How can I do this? 回答1: Something like this, maybe? :%s/\<[-a-z]\++test\>//gc It will ask for each match if you want to replace

Vim & Mac: How to copy to clipboard without pbcopy

阅读更多关于 Vim & Mac: How to copy to clipboard without pbcopy

I have a version of vim with both clipboard and xterm_clipboard support. However, "*y or "+y don't copy to the system clipboard. I know I can use :w !pbcopy (and even create a shortcut for it), but I really want the standard way. I saw fakeclip also, but wish to find a solution that is not fake... Moreover, I wish to not need to use "* or "+ and just use y UPDATE: I just checked using the :reg command. I copied some text In another application then in vim ran the :reg command. The text is not there. I then ran MacVim and :reg showed that "* has the copied text. So something wrong with my vim?

Replace word with what's ready to put in vi/vim?

阅读更多关于 Replace word with what's ready to put in vi/vim?

问题 For example, I have: rm -f $(NAME).elf $(name).d where the second 'name' is a typo, and should also be 'NAME'. So on 'N', I did y w , and then moved to 'n'. I realised that if I now hit c w to change it, I'll be in insert mode - but I thought ah well, it's only one extra key ( ESC ) and then I can just p the corrected version in. But in that case, p did exactly what u would have done, it put 'name' back. I guess because the 'old text' is loaded into the register on change too, which I didn't

阅读更多关于 VI (VIM): delete/change right to left?

问题 I often use "c-t-$char" change-till-character and "d-t-$char" and would love to be able to do the same thing in reverse. An example: cobbler reposync --only=puppetlabs-6Server-x86_64 If my cursor is at the end of the line and I want to delete backwards to the = char. What brought this on is my wanting to move from BASH emacs mode to vi mode. 回答1: You can use T and F for that. For example cT= or dF= etc. 回答2: d-T-$char deletes from the cursor position backwards without deleting $char , d-F-

你是否会和我一样经常碰到这样的情景：在VIM中编辑了一个系统配置文件，当需要保存时才发现当前的用户对该文件没有写入的权限。如果已经做了很多修改，放弃保存的确很懊恼，只好先保存在用户的主目录下，再用sudo mv移动到文件的原始位置，并按需要chown。这样做实在太麻烦了，以下的这个技巧就太方便了。当需要保存时，输入以下的命令： :w !sudo tee % 来源： oschina 链接： https://my.oschina.net/u/103999/blog/33916
