I want to add ' in front and behind my variable and replace one character inside.

Here is my input: peter:chris
Here is my expected output: 'peter-chris'

I have tried, but my code is failing. My echo prints nothing. Code attempt attached.

Appreciate your help.

if [ -n "$string" ]
then
	set string = `echo "'"$string"'" | sed "s/:/-/"`
	echo $string;
fi

Which shell are you using, and how did you set $string before running that code?

In that case, I would have expected the output

peter:chris

and I don't understand why your echo prints nothing

If I change
   set string = `echo "'"$string"'" | sed "s/:/-/"`
to
   string=`echo "'"$string"'" | sed "s/:/-/"`
then I get
'peter-chris'

Although a simpler way to do that could be
echo "'${string/:/-}'"
