linux - Bash: How to build a recursive cowsay -


here's linux command (you might need cowsay application.

cowsay 'moo'

here's command:

cowsay 'moo' | cowsay -n

the result pretty entertaining:

 ______________________________ /  _____                       \ | < moo >                      | |  -----                       | |         \   ^__^             | |          \  (oo)\_______     | |             (__)\       )\/\ | |                 ||----w |    | \                 ||     ||    /  ------------------------------         \   ^__^          \  (oo)\_______             (__)\       )\/\                 ||----w |                 ||     ||

now, of course, it's pretty fun repeat piped command n times. looks little this:

 cowsay 'moo' | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n | cowsay -n

cows nested inside cows saying things

but i'm thinking there must neater way of achieving this. let's want 500 cows saying each other, or 1,000, or 1,000,000. surely don't have keep finger on paste button?

here's question; there way in bash (command or script) recursively pass output of command given number of times?

cowsayn() {     local n=$1     shift     if ((n>1));         cowsay -n | cowsayn $((n-1))     else         cowsay -n     fi } echo 'moo' | cowsayn 500

'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.

android - Unable to generate FCM token from dynamically instantiated Firebase -

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...
