关于Linux系统下PATH设置方法

假设你要执行的程序路径在 /usr/my下
　
　　 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
