问题
I have a bunch of folders and subfolders. Each one contains, amongst other things, a text file called index.yml with useful data. I want to search through all of the different index.yml files to find instances of a search string. I must be able to see a few lines of context and the directory of the index.yml file that was found.
This almost works, but it doesn't give me the filename:
cat `find . -name 'index.yml'`| grep -i -C4 mySearchString
How can I do this and get the filename?
I am stuck on Windows with using msys. Note I don't seem to have full GNU grep, so I can't run grep --exclude or grep -R as suggested in other SO questions.
回答1:
try this:
find -name "index.yml" -exec grep -i -H -C4 pattern {} \;
note: not actually tested under msys.

One possibility (I don't know what msys accepts exactly):
find . -name index.yml -exec grep -i -C4 mySearchString /dev/null {} +
The /dev/null serves to ensure there are at least two pathnames so that the pathname is printed with each match. The -H option to grep has a similar effect.
The -exec...+ construct in find causes multiple pathnames to be passed to a single instance of the command. If it is not implemented, you'll have to use -exec...\;.
