修改 ～/.bashrc 文件，以配置用户自己定义的alias
$> vi ~/.bashrc
显示
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
在文件最后，添加自定义的alias语句
echo "My alias has started successfully!"
echo "Type 'alias' to see more about this!"
# my
alias la='ls -al --color=auto'
# my-end
这次更改需要在下次登录时生效。
若要立即生效，输入：
$> source ～/.bashrc
