Linux操作系统中设置PATH

Linux操作系统中设置PATH过程: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
