假設你要執行的程序路徑在 /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
然後在 fi 後面加下面語句:
export PATH=/root:$PATH
加完後的 .bashrc 內容為:
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export PATH=/root:$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
