I am installing p4v in /opt, but /usr/bin is on my path. Is it possible to create a soft or symbolic link for p4v from /opt to /usr/bin, so I can just type "p4v" since /usr/bin is in my path?

See man ln. To create symlink /opt/foo --> /usr/bin/bar, (i.e., create symlink at /opt/foo which references to file /usr/bin/bar) do:

ln -s /usr/bin/bar /opt/foo

I am using: sudo ln –s /etc/apache2/sites-available/redmine /etc/apache2/sites-enabled/000-redmine getting error: ln: target '/etc/apache2/sites-enabled/000-redmine' is not a directory –  RAJ ... Aug 4 '12 at 7:29
@RAJ...: Perhaps an example can help ln -s /etc/vim/vimrc /home/paf/Copy/Programming/Apps/Tools/Vim –  pablofiumara Nov 11 '13 at 18:31

If the 'p4v' executable is at /opt/bin/p4v, you can simply run:

sudo ln -s /opt/bin/p4v /usr/bin/p4v
sudo chmod ugo+x /usr/bin/p4v

It would be better to add /opt/bin (or wherever the executable is) to your path:

echo "export PATH=\$PATH:/opt/bin" >> ~/.profile

~/.profile would be better for setting $PATH. –  Lekensteyn Aug 8 '11 at 19:30
you can edit /etc/environment to modify PATH system wide. –  Michał Šrajer Aug 8 '11 at 19:44

The error is that you are writing the command wrong. The correct way is

ln -s /<full>/<path>/<to>/<file> /usr/local/bin
