2009-06-01hush: push down expansion var in handle_dollar()Mike Frysinger
Declare the variable in the scope it is used rather than the entire function scope so it's obvious it is only used there. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-01hush: add support for special vars in bracesMike Frysinger
Some people like to use ${?} rather than $?, so make sure we support all the special single char vars that use this form. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-05-27hush: implement `type`Mike Frysinger
Implement support for the POSIX `type` command. Only POSIX stuff is supported here, no bash extensions like -p or -P. In the process, split the $PATH searching code out of builtin_source() and into its own find_in_path() function so we don't duplicate it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
