vim ~/.bashrc

# .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'

<span style="font-family: Arial, Helvetica, sans-serif;">###################</span>

<span style="font-family: Arial, Helvetica, sans-serif;">alias p='ps -ef|grep'</span>

<span style="font-family: Arial, Helvetica, sans-serif;">###################</span>

# Source global definitionsif [ -f /etc/bashrc ]; then        . /etc/bashrcfi

source ~/.bashrc

2、临时改法

alias ll='ls -l'

去掉别名

unalias ll
