copying a line into vim register from terminal command line
vim
Solution
You're trying to execute normal mode commands in command-line mode (this is what +arguments mean). The correct command-line to do what you want would be:
vim '+/foo' '+normal "qyy' myfilename
See `:help +cmd` for a detailed explanations of such arguments.
Problem
I am trying to write a script that will open a file in vim and copy a particular line in it into one of vim's registers. When the script is run again, it will decide to open the file again and then paste the values in vim's registers back in. Effectively, the script is supposed to toggle the value everytime it's run. For example, suppose I wanted to toggle the word "foo" into "bar" when I run the script, and then back to "foo" again if I run the script again. I can get to the word foo by doing: ``` vim '+/foo' myfilename ``` And I know that when I'm inside of vim, I can load 'foo' into the register 'q' by doing ``` "qyy ``` But the following command doesn't work when checking my registers with :reg ``` vim '+/foo' '+"qyy' myfilename ``` What am I doing wrong? Thanks!
