Shell Programming and Scripting

The line is like this
+abc+def+mgh+ddsdsd+sa
i.e. words seperated by +. There is a plus in the beginning.

i want to conver this line to
abc, def, mgh, ddsdsd, sa

please provide the logic in the form of a shell script

Thanks in advance

You can do something like that :

line=+abc+def+mgh+ddsdsd+sa"
new_line=$(echo "$line" | sed 's/^+//;s/+/, /g')

str="+abc+def+mgh+ddsdsd+sa"
echo ${str#?} | tr '+' ','
