Ubuntu – How to collect all the “txt” and “log” files using find

A way (I suspect there may be a better way) is to use grep to return only the those paths which end in your folder name :

locate foldername | grep /foldername$

If I understand correctly what you want to do, this is the solution:

#!/bin/sh

USAGE="Usage: $0 dir file1 file2 ... fileN\nto find all subdirectories of dir that contain all the given files.\n"

if [ "$#" == "0" ]; then
    printf "$USAGE"
    exit 1
fi

ARG=""
DIR=$1
shift

while (( "$#" )); do
  ARG="$ARG -exec test -e \"{}/$1\" \; "
  shift
done

cmd="find $DIR -type d $ARG -print"
eval $cmd

What it does is this:

The use find ... -type d to find all subdirectories (including the directory given as first parameter). The test -e command checks if a file exists. So for a given directory we have to check all the files given in the command line: test -e /path/to/directory/file1 test -e /path/to/directory/file2 test -e /path/to/directory/file3 ... The /path/to/directory is {} - a single result of find. Then the find-parameter -exec can be used to check for a single file. To check for all files several -exec test parameters are needed. So while loop build a list of there parameters, then this list is put together in a single command and evaluated.

Have fun ...
