I am trying to launch vim. I probably created a bad symlink to vim. I used which and alias commands to find out what is happening. Why doesn't it run vim properly?
MacBook-Air:~ miszo97$ which vim
/usr/bin/vim
MacBook-Air:~ miszo97$ vim
-bash: /usr/local/bin/vim: No such file or directory
MacBook-Air:~ miszo97$ alias vim
-bash: alias: vim: not found
command -v vim
shows you how the shell currently handles the command vim.
In your case it is not an alias. It may be a shell function or it has been located at /usr/local/bin/vim earlier but you deleted the file or symlink.
If vim is somewhere else in your $PATH then you must make your shell realize the new location:
hash -d vim
If vim is not in your path then you have to either copy / move or link it there (and run hash -d vim if it is a different location) or create an alias, a shell function or a hash entry for it:
alias vim="/foo/bar/vim"
vim () { /foo/bar/vim ; }
hash -p /foo/bar/vim vim
/usr/local/bin/vimis not just a hashed path? compare the output oftype vimwith that ofwhich vimand executehash -d vimif necessary./usr/bin/vim, at least then we can be sure you actually have it properly installed. Then tryls -l /usr/bin/vim, if the first letter isl, you have overwritten your vim with a symlink somehow. Then show us whatecho $PATHoutputs and I guess double-checking if there is something fishy in /usr/local/bin/ won't hurt withls -l /usr/local/bin/vimbrew install vimto reinstall vim should capable fix automatically.
