centos7 “export: command not found

Question

I have followed a tutorial to install JDK 8 on my computer Centos7 OS, but in the last part I tried to set environment varibles.

In the last part of the tutorial I typed:

echo “export JAVA_HOME=/opt/jdk1.8.0_101” > /etc/profile.d/jre.sh
echo “export JRE_HOME=/opt/jdk1.8.0_101/jre” >> /etc/profile.d/jre.sh
echo “export PATH=$PATH:/opt/jdk1.8.0_101/bin:/opt/jdk1.8.0_101/jre/bin” >> /etc/profile.d/jre.sh

and then I am seeing this when I open the terminal:

bash: $'\342\200\234export':order not found
bash: $'\342\200\234export': order not found
bash: $'\342\200\234export': order not found
[evconsul8@localhost ~]$ 

Path:

[evconsul8@localhost ~]$ echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/evconsul8/.local/bin:/home/evconsul8/bin

After that I Trying to search the cause open ~/.bash_profile

[root@localhost evconsul8]# gedit ~/.bash_profile

Result:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
export JAVA_HOME=/opt/jdk1.8.0_101
export JRE_HOME=/opt/jdk1.8.0_101/jre
export PATH=$PATH:/opt/jdk1.8.0_101/bin:/opt/jdk1.8.0_101/jre/bin

export PATH

Note: In one of my attemps after the error I added manually the lines corresponding to JAVA_HOME, JRE_HOME and PATH=$PATH in the file above. It was ok??

The principal problem I guess it is causing troubles to other apps in my machine.

您应该使用常规的双引号（ " ）将字符串括起来，而不要使用花哨的双引号（ " “ ）。
