關于Linux系統下PATH設置

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 后面加下面語句：

export PATH=/root:$PATH

加完后的 .bashrc 內容為：

# .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

//在命令行下輸入 source .bashrc 執行 .bashrc 生效.

[root@stroller root]# source .bashrc

//查看PATH值：

[root@stroller root]# echo $PATH
