Full Discussion: Test -e not working as expected (by me)
Top Forums UNIX for Advanced & Expert Users Test -e not working as expected (by me) Post 302938169 by MadeInGermany on Thursday 12th of March 2015 03:43:43 PM

I did some tracings.
Indeed test -L does an lstat() i.e. does not try to follow a symlink.
test -e does either a stat() or an access() i.e. follows a symlink and a symlink's symlink... This is meant with "resolve".
In order to test for anything, you need test -L "$file" || test -e "$file".
