Reset to default
Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.
It falls back to sorting by highest score if no posts are trending.
The easiest way is to have grep return just the filenames (
-l instead of
-n) that match the pattern. Run that in a subshell and feed the results to Vim.
vim $(grep -rIl 'xg_icon-*' *)
A nice general solution to this is to use xargs to convert a stdout from a process like grep to an argument list.
grep -rIl 'xg_icon-*' | xargs vi
if you use vim and the -p option, it will open each file in a tab, and you can switch between them using gt or gT, or even the mouse if you have mouse support in the terminal
You can do it without any processing of the grep output! This will even enable you to go the the right line (using
:help quickfix commands, eg.
:cw). So, if you are using bash or zsh:
vim -q <(grep foo *.c)
if what you want to edit is similar across all files, then no point using vi to do it manually. (although vi can be scripted as well), hypothetically, it looks something like this, since you never mention what you want to edit
grep -rnI 'xg_icon-*' | while read FILE do sed -i.bak 's/old/new/g' $FILE # (or other editing commands, eg awk... ) done
vi `grep -l -i findthisword *`
