im using the FZFfind command found on the wiki: https://wiki.vifm.info/index.php/How_to_integrate_fzf_for_fuzzy_finding
however it have problems in some directories like /usr, this is the error i get: https://pastebin.com/vqL9SgnC
Try this variant (adds 2>/dev/null to find command):
2>/dev/null
find
command! FZFfind :set noquickview | :execute 'goto' fnameescape(term('find 2>/dev/null | fzf --height 10 2>/dev/tty'))
