file-counter v0.1.2
file-counter
Recursively count the number of files within a directory, and all of its subdirectories. Apply filters to exclude files or directories from the total.
Install
file-counter
can be used as either a command line utility or included in your
projects or scripts where you need to know the number of files within a directory.
CLI
Install globally so you can run the file-counter
command via the command line
within a directory to get the total number of files within that directory and all
sub-directories.
Via npm:
npm install -g file-counter
countFiles
Method
If you need to get the total number of files for a task progress bar, or you’re
evaluating the number of files within a directory for maintenance purposes within
another script, you can use the countFiles
method.
Via npm:
npm install file-counter
Via yarn:
yarn add file-counter
How to use
You can use file-counter
two different ways, as a command line utility or as a
utility for use within your package or project. Below are a few examples on how
you can use it in those scenarios.
CLI
$ file-counter [options] [dir]
Options
The following options are available both for the CLI use of file-counter
, as
well as for the countFiles
method. Please note that when using the --exclude-*
,
or excludeDirs
, options that the defaults will no longer be applied.
Exclude Files - -f, --exclude-files [...files]
Depending on what you’re doing, you may find the need to exclude certain files from the total that is returned. You can do that by including a comma separated list of file names or regular expressions to exclude from the count tally.
By default, the following files are excluded from totals:
.DS_Store
.DS_Store?
.Spotlight-V100
.Trashes
ehthumbs.db
Thumbs.db
Here’s an example of using the -f
, or --exclude-files
, option:
Exlude any .DS_Store
file and all Javascript (*.js
) files:
$ file-counter -f '.DS_Store,(.*).js'
Exclude Directories - -d, --exclude-dirs [...directories]
The same goes for directories. You can use either the exact directory name or a regular expression to exclude directories, and their files, from being included in the total count.
By default, the following directories are excluded from totals:
.git
node_modules
vendor
Here are a few examples of using the -d
, or --exclude-dirs
, option:
Exclude .git
and node_modules
directories:
$ file-counter -d '.git,node_modules'
Exclude all directories (ie. only tally the files in the root directory):
$ file-counter -d '(.*)'
Verbose - -v, --verbose
Including the --verbose
flag will output file names included in the total count.
$ file-counter -v
countFiles
Method
In addition to the command line utility, you can also use the method that the utility relies on in your own projects and scripts where you would want to know the number of files in a directory.
countFiles({...options}, count = 0)
*Note: count
is there because the method is recursively called while traversing
the directories. Please do not prepopulate that argument unless you want to
increment/decrement the count by that value.
Options
countFiles({
dir: '...',
excludeFiles: ['...',],
excludeDirs: ['...',],
includeLogs: [true|false],
verbose: [true|false],
})
Here’s an example where we use the countFiles
method in combination with the
progress package to show a progress
bar during the processing of a Node script.
import path from 'path';
import { countFiles } from 'file-counter';
import ProgressBar from 'progress';
const ROOT_DIR = path.join(__dirname, '../');
const totalFiles = countFiles({
dir: ROOT_DIR,
});
const bar = new ProgressBar(':bar', { total: totalFiles });
...
(iterate over files, doing stuff)
bar.tick();
...
And, if you’re curious about the progress
package referenced above, you can find
out more about that, here.
