and in emacs you can just redirect the command output to a buffer. or honestly, 99% of the time, I don't even bother redirecting and muck with the output directly in the eshell buffer.
No reason to be rude, I have used VIM for 15 years, I know how it works.
Yes you can pipe stuff in and out, you can do in Emacs as well.
My point being that VIM isn't better than Emacs on this aspect, and they're not like other shell tools where COMMON usage is by piping stuff in and out; they're not like cat, more, wc. They live in their own space.
...huh? I pipe things into vim absolutely all the time.
I don’t mean to be rude but this is exactly the sort of thing OP meant by “people recommending evil don’t understand why people like vi(m)”.
and edit the results as needed.
