Miscellaneous stuff for deco users

Extractor wrappers

deco-diskimage is Zoë Stephenson’s collection of extractor wrappers for filesystem disk images.

A handy shell snippet

Add the following code to your POSIX-compatible shell’s initialization file, ~/.bashrc in the case of bash:

dcd()
	{
	while getopts ace:uv __dcd_out "$@" 2>/dev/null; do :; done
	test $OPTIND = $# || { deco "$@"; return; }

	__dcd_out=`deco "$@"; ret=$?; printf .; exit $ret`
	__dcd_ret=$?
	__dcd_out=${__dcd_out%.}

	case $__dcd_out in
		*/?) cd -- "${__dcd_out%?}" && ls ;;
		 *?) printf %s "$__dcd_out" ;;
	esac
	eval unset __dcd_out __dcd_ret\; return $__dcd_ret
	}

You can then e. g. run dcd -u archive.tar to extract then unlink archive.tar and, if applicable, cd into (presumably) archive/ and call ls.

Note that deco 1.6 or later is needed for this to work.
