bash - How do I get just the app id with PM2? -


say have app named "fizzbuzz". start pm2 start index.js --name="fizzbuzz" --watch. automation purposes i'd id of app. can grep guess seems pm2 have out of box. can't find in docs. instance, i'd this: 

$ pm2 id --name="fizzbuzz" 3

will have use grep , string manipulation in bash accomplish this?

since presumably can't add shell lines pm2, cannot use $$ variable provides current process' id. there way without resorting ps, grep, et al.

as long command pm2 start index.js --name="fizzbuzz" --watch, this:

pm2 start index.js --name="fizzbuzz" --watch & fizz_pid=$!

the ampersand runs pm2 in background. fizz_pid=$! writes process id of program last put background fizz_pid variable. (caveat: adding pipe | after end of pm2 command break this.)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
