I am trying to write a script that shows me if a service is running or not.

command:
service ntpd status | awk '{print $5}'

output:
running...

how can i remove those dots? or is there a better way to find out that a service is running or not?

  • You could use sed to remove the dots. However, service name status is a script that tells you if a service is running or not. Not sure why you would need something else.

  • What do the dots matter? That command gives you want you want which is the status of the service.

You could use the awk's gsub command:



$ service ntpd status | awk '{gsub(/[.]/,"");print $NF}'

running


Using NF since the status word is usually the last word of the output.



The command service is the old way to check services (for systems not using systemctl yet). With systemd use:



systemctl is-active sshd >/dev/null 2>&1 && echo YES || echo NO
