retitle 537283 built-in tests fail in precmd if no command was executed thanks
% precmd_test() { set -x; test -d . && echo . is a directory; set +x; }
% precmd_functions=(precmd_test)
+precmd_test:0> test -d .
+precmd_test:0> echo . is a directory
. is a directory
+precmd_test:0> set +x
% [PRESS CTRL-C]
+precmd_test:0> test -d .
precmd_test:test: argument expected
+precmd_test:0> set +x
The same happens with [ -d . ], but /usr/bin/test and /usr/bin/[
work fine. Thus, there must be something fundamentally out of order
with precmd functions and builtin tests which shows only when precmd
functions are called without a preceding exec() by the shell.
Running an external programme before the test from the precmd
function (e.g. ls >/dev/null) does not work though.
I can reproduce this with zsh -f.
