linux - Bash separation of line with newlines instead of spaces -

-

I have made two of the following commands:

In the past, I listed the contents of the directory and It was stored in it variable The second shows the contents of a variable

Enter image details here

I have now decided That I want to separate listings, not with spaces, but with Newline, I do the following: here Enter image details

Why do I get a mess?

It is worth noting that when I changed the command, I did the work: Enter the image Please describe here

Can anyone please explain, why 0x20 or 32 (I also tried this number) in this case Bash is not treated as space ?

tr simply does not recognize hex but octal will work: < / P> 

  tr '\ 040' '\ n'

and an easy way to show your files 

  shop-to Nologlob ## Optional Printf '% s \ n' * *
