Hi Manuales:

Use formatted printing:

# v="hi"
# printf "%-s \n" $v | cat -etv

...and you will see the space before the neline ($).

p.s. I added some more commentary to your thread here:

We just discussed that in a prior topic of yours.
Those double quotes!
You gotta know when to hold them, when to fold them!

$ v=hi
$ vv=$v" "
$ vvv="hi "
$ echo "==$v==$vv==$vvv=="
==hi==hi ==hi ==

free advice...
bracket variable names to allow arbitrary strings to be glues to them

$ x="${v}test"

THHHHAAAAAAAAANKKKKKKKKKKSS

IT WORKED ...

$ printf "%-s \n" $v | cat -etv
hi $
$ V=`printf "%-s \n" $v | cat -etv`
$ echo $V
hi $
$ echo $V | sed 's/\$//g'
hi
$ echo $V | sed 's/\$//g' | wc -w
1
$ echo $V | sed 's/\$//g' | wc -s
wc: illegal option -- s
usage: wc [-c|-m] [-lw] [name ...]
$ echo $V | sed 's/\$//g' | wc -c
4


Thanks a lot !!!! :)

Sigh, only mundane shell talks.
From the subject line I was excited to witness a phylosophical dispute about infinity, eternity and beyond here.
