15:59:32 JST 2007 o...@sma:/usr/src/sys/i386/compile/SMP i386
Machine Type: i386-unknown-freebsd6.2
Bash Version: 4.0
Patch Level: 24
Release Status: release
Description:
builtin command `command' does not report/execute an expected
command path or description even if `-p' option is specified.
should not report aliases or user defined functions,
but it does.
Repeat-By:
try following commands sequence.
% ls
% ...
% cat /tmp/ls
#!/bin/sh
echo ls-/tmp
% PATH=/tmp:/bin:/sbin:/usr/bin:/usr/sbin
% command -p ls
... <-- /tmp/ls is executed,
but /bin/ls should be
% command -vp ls
/bin/ls
% hash -r
% command -vp ls <-- expected output,
/tmp/ls after hash is cleared
Fix:
apply following patch to builtin/command.def
