[SOLVED] how to print space in for loop bash

lqmsh · 12-09-2022, 12:21 AM

I am trying to print space in for loop by the script below

Code:

#!/bin/bash
for i in - - - - - - up to date; do
   echo -n $i
   sleep 0.5
done

the output I want is
------ up to date
but the script output
------uptodate

How can I print spaces where I want?
thanks in advance.

Put space where you want. In your code you do not print (echo) space at all. Why do you think it will be added automatically?

Code:

echo -n "$i "  # << add a space after $i
