WebjxCom友情提示:新手看招: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

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 后面加下面语句:

export PATH=/root:$PATH

加完后的 .bashrc 内容为:

# .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

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

[root@stroller root]# source .bashrc

//查看PATH值:

[root@stroller root]# echo $PATH
