I am installing oracle database in Ubuntu 16.04. I unzipped the file in /opt, then I tried to create a symbolic link using

sudo ln -s /opt/sqldeveloper/sqldeveloper.sh/usr/local/bin/sqldeveloper

but it shows error

ln: failed to create symbolic link './sqldeveloper': File exists

What should I do?

    Typo? I think you intended to run sudo ln -s /opt/sqldeveloper/sqldeveloper.sh /usr/local/bin/sqldeveloper?.

There is space missing in your command. Use this command (also mention by Thomas in comment).

sudo ln -s /opt/sqldeveloper/sqldeveloper.sh /usr/local/bin/sqldeveloper
