How to run a series of vim commands from command prompt

Question

I have four text files A.txt, B.txt, C.txt and D.txt I have to perform a series of vim editing in all these files. Currently how I am doing is open each files and do the same vi

Answer 1

vim -c  Execute  after loading the first file

Does what you describe, but you'll have to do it one file at a time.

So, in a windows shell...

for %a in (A,B,C,D) do vim -c ":g/^\s*$/d" -c "" %a.txt

POSIX shells are similar, but I don't have a machine in front of me at the moment.

I imagine you could load all the files at once and do it, but it would require repeating the commands on the vim command line for each file, similar to

vim -c "" -c "" -c ":n" (repeat the previous -c commands for each file.)  

EDIT: June 08 2014: Just an FYI, I discovered this a few minutes ago.

vim has the command bufdo to do things to each buffer (file) loaded in the editor. Look at the docs for the bufdo command. In vim, :help bufdo
