How to stop minification of js files in grunt?

I am new to grunt. I have nearly 20-30 js files in my project. I came to know that We are already using grunt to minify and concatenate them. For debug purpose I need to stop minification but retain them in concatenated form. Could any one suggest how to proceed. Any site which has the related tutorials would be helpful.Thanks in advance.

module.exports = function(grunt) {
 var readJSFile = function(data, path){
    var finalArray = [];
    if(path == 'assets/js/'){
        finalArray.push('<%= copy.options.buildFolder %>/JSON-words.js');
    }
    for(var item in data.main){
        finalArray.push('<%= copy.options.buildFolder %>/'+path+data.main[item].file);
    }
    return finalArray;
}
grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    exec: {
        update: {
            command: 'TortoiseProc.exe /command:update /path:"./**" /closeonend:3'
        }
    },
    copy: {
        options : {
            buildFolder : '../../deliverables/<%= pkg.folder %>/<%= grunt.template.today("yyyymmdd") %>-htdocs'
        },
        main: {
            files: [
                {expand: true, src: ['./**'], dest: '<%= copy.options.buildFolder %>'}
            ]
        }
    },

Look in the Gruntfile. There is probably a reference to a task named "min". Try to remove that reference and run grunt again.

For a more detailed answer you need to add the Gruntfile to the question.

Edit: It could also be called uglify . Look for a line like this at the end:

grunt.registerTask('default', ['jshint', 'qunit', 'concat', 'uglify']);

and remove the last option. You might also have to change some file paths.
