Machine Type: x86_64-pc-linux-gnu
Bash Version: 5.2
Patch Level: 21
Release Status: release
Description:
>From the command line
printf "%*s\n" 80 " " | tr " " "*"
does just what I'd expect generating a banner line of asterisks.
However:
foo=$(printf "%*s\n" 80 " " | tr " " "*")
echo $foo
acts very differently; it seems to perform ls or something similar.
The same occurs with the more standard printf "%80s" form.
Repeat-By:
As above.
Fix:
Unknown.
