So I have a script that seeks whether my service vmxd.service exists, and checks its current state loaded,running,active...
I use the following script for that case.
systemctl --all --type service | awk -v pat="$SERVICE" '$0 ~ pat {print $0}'
● vmxd.service loaded failed failed Juniper vMX Router
Bear in mind that $SERVICE="vmxd.service"
The problem is that in some servers, that [●] is not present, so I deducted that by printing the first word {print $1} it would make the trick of grabbing the name.
When I checked my script on another host, now instead of printing vmxd.service as it was the first character on the string, it is now printing [●] and totally breaks my script.
Here is an Output of my Script showing the [●]
[...]
The service file: vmxd.service has been found under /etc/systemd/system/
Check if WorkingDirectory path is correct............................[OK]
Check if service exist...............................................[Found]
Check if ● is loaded...............................................[No]
Check if ● is active...............................................[No]
Enabling service....................................................../init.sh: line 189: command not found
Reloading Service....................................................[No]
Check if 'vmxd.service' has started successfully.....................[Started]
Is there a workaround for this issue? Is there a way to, if [●] is detected ignore without altering the {print $1}. By printing $1 it should say vmxd.service regardless
Normally the output on the servers where my script works are like:
vmxd.service loaded active exited Juniper vMX Router
without the [●].
Note: I have no much idea what that dot actually means, but regardless I just need to ignore that character from my variable running the command
