I have this statement in my code:

for i in $(echo "Hello " $name) ; do echo ${i^} ; done | tr '\n' ' ' ; echo -e "\r" | echo ", bye"

I would like to display space in the terminal, like this:


....Hello Name , bye

(without full stop)


How can I do this?
Thank you for whom will help me.

The meaning of this code is not clear to me, but you could write
EDIT: When I run your unchanged code, I get a space:

(here I would like to live some space, like a tab space)Hello Name , bye

You put echo -n " " or echo -n -e "\t" before the for loop.

Could you please tell us what do you exactly have in mind with this script? I mean, strictly speaking, just would be enough to fulfill your request. Is that $(echo "Hello " $name) just a placeholder for commands you want to put into the real script? Then what would they be?

It looks like a homework for me.
assuming:should do it - if I understand well.

Thank you to everybody so far but I still looking for help.

Thank you to pan64. You give me some right tips.Your code worked partially.

I modified the code in this way:


echo -e "\t\tPlease enter your name?"
read name
name="${name,,}"
for i in $(echo "Hello " $name) ; do echo ${i^} ; done | sed 's/^/\t\t/;s/$/, here is your order:/'

If I enter the name like : mike denver


The output is:

<here come out the right space of two tabs>Hello, here is your order:
<here come out the right space of two tabs>Mike, here is your order:
<here come out the right space of two tabs>Denver, here is your order:

Basically, it create the right space from the left side based on the number of tabs that I put (\t), but it repeats the print line for Hello plus for each names entered. I didn't understand how to put sed command outside.
My expected result should be this:

<here come out the right space of two tabs>Hello, Mike Denver here is your order:

A for loop is a programming statement that allows a section of code to repeat. A bash for loop can iterate over a list or a sequence and in the case of your program it is a list that is created using your command $(echo "Hello" $name). The default separator for a list is a space and if you enter multiple names your loop will be a list like
hello
first name ( mike )
second name ( denver )

And create a line here is your order for each item in the list as posted above and as shown in your output. I assume this is homework and while we should not write the script for you we can try to help with specific problems. I'm not sure your on the right track without seeing the actual assignment.

Hi MichaelK

Thank you for your email.

Anyway, I would like to explain that if I am doing this research, is because I am still learning Unix and I am asking help, just because I am creating my personal code and I would like to make this change even if it is not necessary but I like to learn, and this is the reason because I asked this community help to sort out my curiosity. Thank you anyway for all of you that gave me some of your precious time.

what about this:

At the moment there isn't enough information provided to know why the OP even needs a loop.

My take on it
Example:

Hi shruggy Urrahhhhh ....!!!!!!

You are my hero....!!!!

It works perfectly

Thank you so much everybody
