There is PM2 configuration, /home/foo/someconfig.json
{ "apps": [ { "name": "foo-main", "script": "./index.js", }, { "name": "foo-bar", "script": "./bar.js" }, { "name": "foo-baz", "script": "./baz.js" } ] } Most of the time I want to refer to all of the apps under current namespace, e.g.
pm2 restart foo instead of doing
pm2 restart foo-main foo-bar foo-baz Bash brace extension cannot be used because apps may run in Windows.
Doing pm2 restart /home/foo/someconfig.json isn't a good option, because it takes some time to figure out config file path, it may differ between projects and even change its location.
Can foo-* apps be merged into single foo app or be referred altogether in another reasonable way?

It seems that pm2 itself doesn't support wildcard-based restart, but it is not complex to make a simple script to do it using pm2 programmatic API.
Here is a working script that demonstrates the idea:
var pm2 = require('pm2'); pm2.connect(function(err) { if (err) { console.error(err); process.exit(2); } pm2.list(function(err, processDescriptionList) { if (err) throw err; for (var idx in processDescriptionList) { var name = processDescriptionList[idx]['name']; console.log(name); if (name.startsWith('foo')) { pm2.restart(name, function(err, proc) { if (err) throw err; console.log('Restarted: '); console.log(proc); }); } } }); }); To make it fully functional, it is also necessary to pass foo as command-line argument (now it is hard-coded) and handle exit (now it works, but doesn't exit on finish).
Here is the full code example, including small sample apps and config.
