I recently decided that I wanted to learn more about Unix. I found this article and have been reading through it. It's pretty good thus far. I arrived at the part where they're discussing how to remove files and how you can customize terminal so that it prompts you before removal. I thought that would be good to have since I'm fairly new to Unix/Terminal. I inputted the command they gave but it will not work and I was wondering if anyone could help? Their discussion of the situation is below. Thanks in advance! I guess I should have said specifically which commands weren't working. I type: % echo "alias cp cp -i \\!\*" >> ~/.tcshrc % echo "alias mv mv -i \\!\*" >> ~/.tcshrc % echo "alias rm rm -i \\!\*" >> ~/.tcshrc and they are accepted with no errors but the changes never go into effect. I have opened new terminal windows and closed and reopened terminal.
