I'm trying to install Eclipse "by the book" in /opt, but when trying to access /opt, it seems that /opt directory doesn't exist in Ubuntu 14.04:
$ cd /opt/ bash: cd: /opt/: No such file or directory $ ls -a / . bin cdrom etc initrd.img lib lost+found mnt root sbin sys usr vmlinuz .. boot dev home initrd.img.old lib64 media proc run srv tmp var vmlinuz.old
Why is the /opt folder missing? How to re-create one if applicable & what are the permissions to apply?
