Echo working funny
Hello, this is my first post and question. I have search before for this problem but didn't find anything similar.

My case: I have a string inside the variable string1 like this:

string1="lala lele lili lolo lulu"

When I do echo of it, it appears like this:

echo $string1
lala lele lili lolo lulu

But if I do echo with characters before and after, it appears like this:

echo "123 $string1 123"
123 lala
lele
lili
lolo
lulu 123

What's the problem?

NOTE: I have generated string1 with an AWK loop, but I have already test it with this example without AWK and the same happends!

Help me please!

Regards.

I will answer myself
It DOES NOT happend if you do it like in my example.

I think is something related with AWK. Is it inserting carriage returns between words? This is my AWK code.

It's runned in HP-UX. swList contains a list of packages and the comand swlist gives you the same list, but with 3 or more colums:
  • The first one the name of the pacjage binari.
  • The second one the version.
  • The third one and the rest the package full name.

Code:
for package in $swList; do

    # Package name
    package_name=$(swlist | grep "$package" | awk '{
    
        word_count=3
        
        while (word_count <= NF) {
            
            print $ word_count
            
             word_count++
            
        }
    }')
    
    # Package version
    package_version=$(swlist | grep "$package" | awk '{ print $2 }')
    
    echo "software^^^$oa_package_name^^^$oa_package_version^^^"

done

Help!

Thanks!

But it does not work with the string I made using that AWK code...

And there is a mistake in the code I put in my previous post. The last code line is:

Code:
echo "software^^^" "$package_name" "^^^" "$package_version" "^^^"

done

Just in case someone thought that was the problem Smilie

Well, I don't know why it happens but I have solved the problem doing the echo like this:

Code:
echo "software^^^"$(echo $oa_package_name | tr "\n" " ")"^^^$oa_package_version^^^ ^^^ ^^^ ^^^^^^ ^^^"

tr converts the carriage return into a space character.

Regards.

This actually unquotes the variable!
Code:
echo "123 "$string1" 123"

Can you post the whole script and state you Operating System and Shell?

Use printf in your awk code instead of a print statement, replace this:

Code:
print $word_count

with:

Code:
printf "%s " $word_count

hehe, yes! It does unquote the variable, because of that I put a pipe after the AWK loop like this:

Code:
        word_count++
            
        }
    }' | tr "\n" " ")

This worked fine!

HP-UX, KSH. The script is... too long to be posted! hehehe

Thank you very much anyway Smilie[COLOR="#738fbf"]

Didn't work, got this message in return:

Code:
awk: There are not enough parameters in printf statement %s sudo.
 The input line number is 1.
 The source line number is 7.

Trying to find the solution... this looks fancier than pipe the exit to tr statement Smilie

Not sure what you were trying to achieve here but beware that "swlist" on its own lists the bundles. Each bundle can contain multiple packages.
