关于Linux系统下PATH设置

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 Webjx.Com

保存退出！ Webjx.Com

[root@stroller root]# source .bashrc

完整例子：

[root@stroller root]# vi .bashrc

# .bashrc Webjx.Com

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

Webjx.Com

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

然后在 fi 后面加下面语句： Webjx.Com

export PATH=/root:$PATH

加完后的 .bashrc 内容为：

# .bashrc Webjx.Com

# 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

Webjx.Com

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

[root@stroller root]# source .bashrc

//查看PATH值： 网页教学网

[root@stroller root]# echo $PATH Webjx.Com
