JS String not behaving as expected

Question

I am creating file paths like so:

'/Users/User/Documents/dev/engineerappcopy/VGimages/'+deviceName+'.png'

these file paths are passed to a function as parameters, this function uses the file path to perform a command on the terminal.

However, this string seems to split into 2 parts when used by the function. presenting this error:

exec error: Error: Command failed: /bin/sh -c adb pull /sdcard/nexLogin.png /Users/User/Documents/dev/engineerappcopy/VGimages/josh
.png

/bin/sh: line 1: .png: command not found

this is because '.png' has been separated from the main string.

deviceName may contain line break or something.. but please post your question and your efforts in resolving the issue — Ovidiu Dolha

Remove the new line character from the end of the deviceName variable. You should probably use the trim method to do this.

'/Users/User/Documents/dev/engineerappcopy/VGimages/'
+ deviceName.trim()
+ '.png'
