findjs -- Walk a file hierarchy, listing or grepping matching files

findjs is a CLI tool modeled after the unix tools FIND(1) and GREP(1). Like find, it can walk a file hierarchy and print to stdout the names of all files that satisfy some simple filters. findjs can also run egrep on each file.

findjs can't do anything that can't be done with find and grep, but it has some simple defaults that make it more convenient for node development. Those defaults are:

1. Return only javascript files, i.e files with the extension .js.
2. Do not search within any node_modules directory.
3. Do not search within any .git directory.

These defaults can be overridden using the options --file-match and --dir-match.

Examples

List all .js files under the current directory, but omitting the .git and node_modules directories:

$ findjs
index.js
lib/descendents.js

Grep all .js files under the current directory for a pattern:

$ findjs -g exports
index.js
1:module.exports = require('./lib/descendents.js');

lib/descendents.js
69:module.exports = {

List all .js files containing a pattern (like grep -l):

$ findjs -m function
lib/descendents.js
