Use & (ampersand) in single line bash loop I have been using this command successfully, which changes a variable in a config file and then executes a Python script within a loop: for((i=114;i<=255;i+=1)); do echo $i > numbers.txt; python DoMyScript.py; done As each `DoMyScript.py` instance takes about 30 seconds to run before terminating, I'd like to relegate them to the background while the next one can be spawned. I have tried what I am familiar with, by adding in an ampersand as below: for((i=114;i<=255;i+=1)); do echo $i > numbers.txt; python DoMyScript.py &; done However, this results in the below error: -bash: syntax error near unexpected token `;'

Drop the `;` after `&`. This is a syntactic requirement


for((i=114;i<=255;i+=1)); do echo $i > numbers.txt;python DoMyScript.py & done
