Author: jilles Date: Tue Sep 1 13:19:15 2020 New Revision: 365037 URL: https://svnweb.freebsd.org/changeset/base/365037 Log: sh: Write absolute path in command -vV and type POSIX is pretty clear that command -v, command -V and type shall write absolute pathnames. Therefore, we need to prepend the current directory's name to relative pathnames. This can happen either when PATH contains a relative pathname or when the operand contains a slash but is not an absolute pathname.
