You're right. I don't know. I tried with gambas 1.9.49:

PUBLIC SUB _new()
  
  SHELL "mkdir -v hello >&1 | head -c5" 
      
END

'head' doesn't work. Also

PUBLIC SUB _new()
  
  DIM sOutput AS String
  
  SHELL "mkdir -v hello >&1" TO sOutput
  PRINT sOutput
      
END
  
sOutput is blank. 

Very strange. Probably a bug(?).
