Korn Shell - Echo out a trailing space

[TunaAdmiral]

Korn Shell. How the heck do you echo out a trailing space?

rmt="/dev/rmt1"
output=$(echo $rmt" ")

That's not working. It's gotta be something simple, I just can't figure it out.

Any help would be appreciated.

Thanks!

Hi

Actually that does echo out the trailing space, but is lost almost immediately. Use double quotes ( " ) around the whole evaluate thing :

output=[red]"[/red]$(echo $rmt" ")[red]"[/red]

That worked! Thank you very much! I'll be adding that to my bag of tricks.

[tt]output="${rmt} "[/tt]

gets you the same result as above I should think...

Hi

First I started to post the same. But then I thought Mikeymac's example is too simple to be real, so maybe is just a simplified reproduction. That [tt]echo[/tt] in sub-process reminds me the pathname expansion :

[red]rmt='*.ext'[/red]

output="${rmt} "

Of course, if my theory is wrong and there is nothing expandable in rmt's value, p5wizard's suggestion is the preferred one.
