Find first match in every folder branch respectively

rated 0 times [ 0] [ 0] / answers: 1 / hits: 924 / 2 Years ago, thu, february 3, 2022, 4:38:45

Given the following folder layout:

Current_folder

└── FolderA

|   └── CMakeList.txt

|   └── FolderAA

|       └── CMakeList.txt

|

└── FolderB

|   └── FolderBA

|   |   └── CMakeList.txt

|   |   └── FolderBAA

|   |       └── CMakeList.txt

|   |

|   └── FolderBB

|       └── CMakeList.txt

|

└── FolderC

    └── CMakeList.txt

    └── FolderCA

        └── CMakeList.txt

How can I use find (or any other tool) to produce an output similar to:

Current_folder/FolderA/CMakeList.txt

Current_folder/FolderB/FolderBA/CMakeList.txt

Current_folder/FolderB/FolderBB/CMakeList.txt

Current_folder/FolderC/CMakeList.txt

Meaning that the search is stopped after a match with the literal "CMakeLists.txt" for each recursive folder branch respectively.

What worked for me was the following bash script:

#!/bin/bash

file_of_interest="CMakeList.txt"

latest_directory_wih_match=""



for current_directory in $(find -type d);

do

  if [[ (${latest_directory_wih_match} == "") || (! ${current_directory} == ${latest_directory_wih_match}*) ]];

  then

    if [ -f ${current_directory}/${file_of_interest} ]

    then

      latest_directory_wih_match=${current_directory}

      echo ${latest_directory_wih_match}/${file_of_interest}

    fi

  fi;

done

@dessert's answer worked for the minimal example above as well. Using it on my actual folder structure (~4000 folders) it was still giving wrong results. I'm not sure why, to be honest.

When I tried @muru's solution it wouldn't stop executing. I guess the function calling itself isn't aborting properly? Not sure about the reason here either.

PS: In an actual CMake Project the file is actually called "CMakeLists.txt" (note the extra s in the end). I spotted this error only after answers were already provided.
