Trying to create a symbolic link in OS 10.14.6 I'm trying to install a symbolic link but when I enter the command I think should work ("sudo ln -s /Applications/harris/idl87/lib/xop/xop2.4/xop /usr/local/bin/xop"), I get no response at all. ????
It's a Unix thing: no news is good news. The symbolic link is likely there. Try ls -l /usr/local/bin/xop and see if its there. The -l flag runs ls so that it draws an arrow back to what it links to.
