linux - How to write systemd environment variables value which contains = -


in systemd units file, have environment content key=iamvalue=abc, can see value iamvalue=abc contains =.

for situation, how can write unit files?

i have tried following, seems invalid:

[unit] description=...  [service] workingdirectory=... execstart=... restart=always restartsec=10                                           syslogidentifier=... user=root environment=key="iamvalue=abc"

i tested works in test.service file:

[unit] description=hi  [service] type=oneshot environment=key="iamvalue=abc" execstart=/bin/bash -c "/bin/echo key:$key"

if run , journalctl -u test, can see key containing equal sign works.

i've proposed update official systemd docs better clarify case.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
