How to remove newline from variable

Setup, Configuration and Use Scripts & Rules

Hello,

I run some script in DSL language

var azimuth_open_cuisine = 400
var azimuth_close_cuisine = 200

var azimuth_open_salle = 400
var azimuth_close_salle = 200
  
var azimuth_open_TV = 50
var azimuth_close_TV = 200
  
var azimuth_open_cour = 400
var azimuth_close_cour = 200

val state = executeCommandLine(java.time.Duration.ofSeconds(1), "cat", "/home/franck/canicule/state.txt")
logInfo("test",state)
  
if (state == "ON")
{
  logInfo("test","success")
  if ((DonneesAstroduSoleil_Azimut.state as Number).intValue > azimuth_open_TV) 
  {
  shellyswitch25c46c01192168115_Alimentation.sendCommand("ON")
  //executeCommandLine("/home/franck/canicule/tv_open.sh")
  }
}

My file /home/franck/canicule/state.txt contains “ON” string. In log I see that variable “state” is indeed set to “ON” but with a newline. Making the condition if(state == “ON”) fail.

07:22:47.108 [INFO ] [org.openhab.core.model.script.test   ] - ON

My question is how I can remove the newline when I read the content of file with cat ? Or how can I parse the variable content afterwards to remove it?

Thanks

Just use String.strip() :slight_smile:

E.g

if (state.strip() == "ON")

Or even

val state = executeCommandLine(java.time.Duration.ofSeconds(1), "cat", "/home/franck/canicule/state.txt").strip()

Thanks, works like expected!
