Little Node script which gets a list of teams from a CSV file, then copies and renames icons for those teams.

copy-team-icons.js

var q = require('q');
var copy = q.denodeify(require('fs-extra').copy);
var exists = require('fs-extra').existsSync;
var csv = require('csv');
var reduce = require('underscore').reduce;

function getTeams() {
    var deferred = q.defer();
    var teams = [];
    csv()
        .from('./teams.csv', { columns: ['sport', 'id', 'name', 'shortName'] })
        .transform(function (row, index) {
            teams.push(transformRow(row));
        })
        .on('end', function () {
            deferred.resolve(teams);
        });
    return deferred.promise;
}

function transformRow(row) {
    return {
        id: row.id,
        sport: row.sport.toLowerCase(),
        shortName: row.shortName.toLowerCase()
    };
}

function copyTeamIcons(teams) {
    reduce(teams, function (copyTeamIcon, team) {
        return copyTeamIcon.then(function () {
            var src = './orig/' + team.sport + '/' + team.shortName + '.png';
            var dest = './result/' + team.sport + '/' + team.id + '.png';
            if (!exists(src)) {
                return q();
            }
            console.log('Copying icon for team: ' + team.shortName);
            return copy(src, dest);
        });
    }, q());
}

getTeams().then(copyTeamIcons);
