i'm trying to create a phonebook using bash script and i would like to ask how to delete only one contact...
1
Here is my code but when I run it it deletes all the contacts that begin with the variable name (name_delete).
read -p "please enter the contact name you want to delete:" name_delete
sed -i /$name_delete/d database
echo "the contact is deleted" ;;
bash scripts

Why reinvent the wheel if there are excellent tools available, e.g. khard and ppl? Or is this merely a training task, not really about a phonebook and your question actually is how to match a full line with sed? If the latter,sed -i /^$name_delete$/d databaseshould do the trick. In any case, please edit and clarify!

If I’m right about what you’re question actually is, please edit and add example lines fromdatabase, especially those which are getting deleted.

Hmmm. This reads like a homework problem.

@user535733 Those are not off-topic per se, and OP clearly made efforts to solve the task on their own, showed what they got and mentioned a precise problem.
