删除bash中的换行符

Question

I'm writing a script to automatically manage my git email configuration. Within my script I would like to output a message notifying the user that the email configuration has changed. I am using the command git config user.email to get the new email address. However, it prints it to a newline. I would like to print it to the same line as my message.

This is what I have now:

    echo "Email not configured to Work in Work directory.";
    git config user.email "myworkemail@myworkemail.com"
    echo "Git email configuration has now been changed to "
    git config user.email

Answer 1

Just use a subshell substitution like this:

echo "Email not configured to Work in Work directory.";
git config user.email "myworkemail@myworkemail.com"
echo "Git email configuration has now been changed to \"$(git config user.email)\""
