export

declare -x HISTCONTROL="ignoredups"

declare -x HISTSIZE="1000"

declare -x HOME="/root"

declare -x HOSTNAME="bogon"

declare -x KDEDIRS="/usr"

declare -x LANG="zh_CN.UTF-8"

declare -x LESSOPEN="||/usr/bin/lesspipe.sh %s"

declare -x PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin"

declare -x PWD="/etc/profile.d"

declare -x QTDIR="/usr/lib64/qt-3.3"

...................

单独查看path

用echo $PATH

[root@bogon profile.d]# echo $PATH

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

临时添加

export PATH=/usr/local/php/bin:$PATH

永久添加

vim /etc/profile

在文档最后，添加:

export PATH="/usr/local/php/bin:$PATH"

保存，退出，然后运行：

source /etc/profile

不报错则成功
