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 a symlink at /usr/bin/bar which references the original file /opt/foo, use:
ln -s /opt/foo /usr/bin/bar
You would need to apply the above command as root (i.e. with sudo).

I am using:
sudo ln –s /etc/apache2/sites-available/redmine /etc/apache2/sites-enabled/000-redminegetting 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 -
4I though César wanted to put his files in the /opt and /usr/bin to have the symbolic link, not other way around. – mishap Nov 26 '15 at 23:41

4@mishap is right as far as I'm concerned. It's the other way around. – Daniel Szmulewicz Dec 18 '15 at 17:05

2@kevinmicke after your explanation finally realized that the explanation of the answer was stated in reverse order from the command, making my brain (and others') read it backwards – Andrew Mar 7 '18 at 21:00

The error is that you are writing the command wrong. The correct way is
ln -s /<full>/<path>/<to>/<file> /usr/local/bin

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
reset

Check the software location by this.
which application-name #replace for the application you are looking for
for example
which skype
output will be this.
/usr/bin/skype
To create the soft link. for example you want to create the soft link for skype on your desktop
ln -s /usr/bin/skype ~/Desktop/
For more information about ln.
man ln
or
ln --help

ln -s -n ./TargetDirectory ./Nickname
Note, this works if you both nodes are below you in the same tree. You can use relative notation
- -s command makes it a symbolic link
- -n makes it possible de create a folder-type symlink

Welcome to askubuntu.com. In this case the
$to indicate a command line prompt is a style choice, and not likely to be a problem. However bear in mind that including things in a code block other than the code and its output can cause confusion. – J. Starnes Dec 12 '17 at 0:42

If it is saying target is not a folder, it means there are spaces in your folder names eg: New Folder has a space
You need to edit the path and add a backslash \ after every space in the paths
eg:
ln -s /opt/bin /usr/var/New\ Folder

I have found that it is easier to go to where you want the link to be and then create the link using sudo ln -s /path/to/source/file, than doing ln -s target source.
So in your case I would do cd /usr/bin then sudo ln -s /opt/bin/pv4. The other way has not been working in my case.

This template was more helpful for me than the above answers. Probably not more correct, just less obfuscated:
ln -s <path/to/real/file-or-folder> <symlink path>
Just replace the parts in <>'s
