the stat command has lots of format sequence options,
similar to the date command, uses the -c option
followed by %_ where _ is one of the "format sequence"
options; for examples:
$ stat -c %A ~
$ stat -c %A%x ~
$ stat -c %A%x%U ~
the man page suggests using
$ info coreutils 'stat invocation'
which presents a lot of invocation for those who can
use emacs editing commands.
thanks for that, rick.
