What should I do if I still get a prompt when setting rf in cp in Linux?

There are two solutions: 1. Use "vi ~/.bashrc" to modify the "/.bashrc" file, and add "#" before "alias cp='cp -i'" to comment it Just delete it, save and exit, and then log in again; 2. When using the cp command, add "\" before "cp" to remove the prompt.

What should I do if the rf setting in Linux still prompts?

By default, when cp overwrites, no matter what parameters -f or the like are added, it still prompts whether to overwrite.

The reason is: The server will add the alias alias cp=’cp -i’ by default. When you execute cp, it actually executes cp -i.

[root@ltt01 ~]# alias
alias cp='cp -i'
alias egrep='egrep --color=auto'
alias fgrep='fgrep --color=auto'
alias grep='grep --color=auto'
alias l.='ls -d .* --color=auto'
alias ll='ls -l --color=auto'
alias ls='ls --color=auto'
alias mv='mv -i'
alias rm='rm -i'
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'

cp cancels the prompt information and directly overwrites it. The user does not need to hit y to interact, which is very important when the script is executed.

The following are two ways to solve this problem.

Method 1: Disable aliases

[root@ltt01 ~]# vi ~/.bashrc

Add "#" before alias cp='cp -i' to comment out this OK, :wq! Save and exit, then log in again.

Method 2: Add \ before cp

[root@ltt01 ~]# \cp 1.txt /back/1.txt 
[root@ltt01 ~]#
