Yes, to test for file existence, the syntax is
[ -e "$file" ] || [ -L "$file" ]
ls -d -- "$file" > /dev/null 2>&1
But even then, if it returns false, that doesn't necessarily
mean the file doesn't exist. It could also be that it's
impossible to tell. If you remove the 2>&1 above, the error
message would help you differentiate between the cases.
If using zsh instead of bash, you can also check the $ERRNO
variable to see if [ -e ] failed because of ENOENT or something
