finder

This is essentially locate from findutils but for local directories.

The program recursivly searches for files and builds a database which can be queried for filenames.

Usage

usage: finder [OPTIONS] [FILENAME]
OPTIONS
        --help          display usage information
        --version       display version information
    -r, --rebuild       rebuild cache
    -l, --list          list all filepaths from the cache

Examples

Finder can be used to locate all filepaths in a directory that have the same filename:

$ mkdir -p a/b/c
$ touch foo.txt a/bar.txt a/b/foo.txt a/b/c/bar.txt
$ finder --rebuild                                      # rebuild the cache
$ finder foo.txt                                        # search for 'foo.txt'
./foo.txt
./a/b/foo.txt
$ finder --list                                         # list all cached files
./foo.txt
./a/bar.txt
./a/b/foo.txt
./a/b/c/bar.txt
$ touch bar.txt
$ finder --list                                         # finder doesn't know about './bar.txt'
./foo.txt                                               # until the cache is rebuild
./a/bar.txt
./a/b/foo.txt
./a/b/c/bar.txt

The --list option can be used with grep or other utilities to search for more complex patterns:

$ mkdir -p a/b/c
$ touch foo.txt a/bar.txt a/b/foo.png
$ finder --rebuild --list | grep '.txt$'                 # find all the files that have the file
./foo.txt                                                # extension '.txt'
./a/bar.txt
