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

<ccid_nobr>

<ccid_code>export PATH=/usr/my:$PATH# .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfiexport PATH=/usr/my:$PATH

保存退出！

[root@stroller root]# source .bashrc

完整例子：

[root@stroller root]# vi .bashrc

<ccid_nobr>

<ccid_code># .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfi

然后在 fi 后面加下面语句：

export PATH=/root:$PATH

加完后的 .bashrc 内容为：

<ccid_nobr>

<ccid_code># .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfiexport PATH=/root:$PATH

//在命令行下输入 source .bashrc 执行 .bashrc 生效.

[root@stroller root]# source .bashrc

//查看PATH值：

[root@stroller root]# echo $PATH
