I am working on my project using network simulator2. I installed it and everything is fine. I attempted to create a symbolic link between this installation and
/usr/bin, so I could invoke the software by running
ns from the command-line. Namely, I ran:
sudo ln -s /home/vinaychalluru/ns-allinone-2.34/ns-2.34/ns /usr/bin/ns
which generated the following output:
ln: creating symbolic link '/usr/bin/ns': File exists
How can I delete the already created symlink or can I replace it with any other commands?
