環境變量查看與設置php
查看vim
exportless
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 LOGNAME="root"
declare -x MAIL="/var/spool/mail/root"
declare -x OLDPWD="/usr/local/php/bin"
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"ide
...................ip
單獨查看path文檔
用echo $PATHqt
[root@bogon profile.d]# echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/binit
臨時添加pip
export PATH=/usr/local/php/bin:$PATHclass
永久添加
vim /etc/profile在文檔最後，添加:export PATH="/usr/local/php/bin:$PATH"保存，退出，而後運行：source /etc/profile不報錯則成功
