假设你要执行的程序路径在 /usr/my下
export PATH=/usr/my:$PATH# .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfiexport PATH=/usr/my:$PATH |
保存退出！
[root@stroller root]# source .bashrc
完整例子：
[root@stroller root]# vi .bashrc
# .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:$PATH
加完后的 .bashrc 内容为：
# .bashrc# User specific aliases and functionsalias rm='rm -i'alias cp='cp -i'alias mv='mv -i'# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfiexport PATH=/root:$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
