Function: dired-mark-files-regexp

dired-mark-files-regexp is an interactive and byte-compiled function defined in dired.el.gz.

Signature

(dired-mark-files-regexp REGEXP &optional MARKER-CHAR)

Documentation

Mark all files matching REGEXP for use in later commands.

A prefix argument means to unmark them instead.
. and .. are never marked.

If the region is active in Transient Mark mode, mark files only in the active region if dired-mark-region is non-nil.

REGEXP is an Emacs regexp, not a shell wildcard. Thus, use \.o$ for object files--just .o will mark more than you might think.
