export PATH=/usr/my:$PATH
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export PATH=/usr/my:$PATH
保存退出！
[root@stroller root]# source .bashrc
完整例子：
[root@stroller root]# vi .bashrc
# .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
然后在 fi 后面加下面语句：
export PATH=/root：$PATH
加完后的 .bashrc 内容为：
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export PATH=/root:$PATH
