“yes” is supposed to run without end, lol!
How to kill a runaway process.
Assuming logged into Glitch, open a browser tab to this url, putting in your project name at the end …
https://glitch.com/edit/console.html?myproject
This opens a console, do the following
$ ps -aux
Should show something like this, with lots more rows …
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
app 204 0.0 0.0 19956 3732 pts/2 S 08:50 0:00 -su
app 217 0.0 0.0 6008 652 pts/1 R+ 08:51 0:01 yes
app 218 0.0 0.0 36084 3192 pts/2 R+ 08:51 0:00 ps -aux
Find the offending process, read its process id (PID) from the second column, then tell it to be killed …
$ kill -9 217
If there is no error message, just another prompt, then it worked.
That’s it, the editor will hopefully recover. You can check its status from Tools > Container Status.
Warning like most linux commands, kill can mess up your server if you use it incorrectly, and can damage your hearing if you put it in your ear.
