How to create a soft or symbolic link?

Question

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-redmine getting error: ln: target '/etc/apache2/sites-enabled/000-redmine' is not a directory – RAJ ... Aug 04 '12 at 07:29
@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

The Ubuntu documentation says " Creates hard links by default, symbolic links with --symbolic." Will the above solution create a symbolic link as asked by OP? – dev May 26 '15 at 05:27

I 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

@mishap is right as far as I'm concerned. It's the other way around. – Daniel Szmulewicz Dec 18 '15 at 17:05
Could you explain what is a link that is not symbolic? What is the difference between ls file ../other and cp file ../other. I was missing the -s option for quite some time now and got frustrated... – Augustin Riedinger Jun 01 '16 at 07:30

is this answer not backwards????????? not just for the OP, but for anyone trying to use it??? – Andrew Feb 24 '18 at 02:14
@Andrew This is correct for creating a symbolic link /usr/bin/bar that points to file/folder /opt/foo. Per 'man ln, the target file/folder comes first, then the link name:ln [OPTION]... [-T] TARGET LINK_NAME (1st form)` – kevinmicke Mar 07 '18 at 20:18

@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 07 '18 at 21:00
Note that target must be absolute not relative paths – Diego Andrés Díaz Espinoza Sep 14 '18 at 01:13
NOTE: Pay attention in creating links with relative paths; you must make the target relative to the link itself, not the directory you're running the command. – MAChitgarha Jan 25 '19 at 13:40

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

~/.profile would be better for setting $PATH. – Lekensteyn Aug 08 '11 at 19:30
you can edit /etc/environment to modify PATH system wide. – Michał Šrajer Aug 08 '11 at 19:44

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

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

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 00:42

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.

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
