Find directories where a text is found in a specific file - linux

Question

How can I find the directories where a text is found in a specific file? E.g. I want to get all the directories in "/var/www/" that contain the text "foo-bundle" in the composer.json file. I have a command that already does it:
find ./ -maxdepth 2 -type f -print | grep -i 'composer.json' | xargs grep -i '"foo-bundle"'
However I want to make an sh script that gets all those directories and do things with them. Any idea?

find
Your current command is almost there, instead off using xargs with grep, lets:
Move the grep to an -exec
Use xargs to pass the result to dirname to show only the parent folder
find ./ -maxdepth 2 -type f -exec grep -l "foo-bundle" {} /dev/null \; | xargs dirname
If you only want to search for composer.json files, we can include the -iname option like so:
find ./ -maxdepth 2 -type f -iname '*composer.json' -exec grep -l "foo-bundle" {} /dev/null \; | xargs dirname
If the | xargs dirname doesn't give enough data, we can extend it so we can loop over the results of find using a while read like so:
find ./ -maxdepth 2 -type f -iname '*composer.json' -exec grep -l "foo-bundle" {} /dev/null \; | while read -r line ; do
parent="$(dirname ${line%%:*})"
echo "$parent"
done
grep
We can use grep to search for all files containing a specific text.
After looping over each line, we can
Remove behind the : to get the filepath
Use dirname to get the parent folder path
Consider this file setup, were /test/b/composer.json contains foo-bundle
➜ /tmp tree
.
├── test
│   ├── a
│   │   └── composer.json
│   └── b
│   └── composer.json
└── test.sh
When running the following test.sh:
#!/bin/bash
grep -rw '/tmp/test' --include '*composer.json' -e 'foo-bundle' | while read -r line ; do
parent="$(dirname ${line%:*})"
echo "$parent"
done
The result is as expected, the path to folder b:
/tmp/test/b

In order to find all files, containing a particular piece of text, you can use:
find ./ -maxdepth 2 -type f -exec grep -l "composer.json" {} /dev/null \;
The result is a list of filenames. Now all you need to do is to get a way to launch the command dirname on all of them. (I tried using a simple pipe, but that would have been too easy :-) )

Thanks to #0stone0 for leading the way. I finally got it with:
#!/bin/sh
find /var/www -maxdepth 2 -type f -print | grep -i 'composer.json' | xargs grep -i 'foo-bundle' | while read -r line ; do
parent="$(dirname ${line%%:*})"
echo "$parent"
done
