I want to know if there is a brief way to check the last 50 lines about a service that threw an error on restart.
$ sudo service nginx restart
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
I use an alias for checking that, tho I forget what the flags do.
alias jrn='sudo journalctl -eu'
$ jrn nginx
