Symlink on /usr/local/bin/ not working

Can someone explain why this is not working??? I don't get it.

$ echo $PATH
/usr/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

As you can see, I have /usr/local/bin in there.

Then the error:

$ cmake
-bash: cmake: command not found

But I do have a symlink:

$ ls -la /usr/local/bin/
total 8
drwxr-xr-x  2 root root 4096 Mar 27 09:07 .
drwxr-xr-x 10 root root 4096 Jan 23 23:23 ..
lrwxrwxrwx  1 root root   20 Mar 27 09:07 cmake -> /opt/cmake/bin/cmake

And in fact, running it from inside the directory it works:

cd /usr/local/bin/
./cmake 

Any ideas?

Of course, if I edit my .bashrc and I add a line like:

export PATH="/opt/cmake/bin:$PATH"

Then it works. But that's not what I want to do.

Thanks!

There could be multiple reasons, here what you can do to check them:

1. Check that the symlink target is executable with this command ls -la /opt/cmake/bin/cmake if not, give the proper rights sudo chmod +x /opt/cmake/bin/cmake.
2. there can be another executable named cmake in the directories listed in your PATH variable, to check do this which -a cmake.
3. Check that there is not a single errors PATH variables, things like extra spaces.
4. Verify the symlink pointing readlink -f /opt/cmake/bin/cmake
5. Check if /opt/cmake/bin is in your PATH variable
6. Check that /opt/cmake/bin is not corrupted
7. Check in a different shell
