alias

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

 

vim ~/.bashrc

寫入相應的alias後，就能夠永久生效了

另外該文件是readonly  輸入:set noreadonly+:wq或者:wq!保存

 

保存文件後，運行：

source ~/.bashrc
