(C-a h)
Writes out the currently displayed image to the file file, or,
if no filename is specified, to hardcopy.n
in the default directory, where n is the number of the
current window. This either appends or overwrites the file if it
exists, as determined by the hardcopy_append command.
If the option -h is specified, dump also the
contents of the scrollback buffer.
(none)
If set to ‘on’, screen will append to the
hardcopy.n files created by the command hardcopy;
otherwise, these files are overwritten each time.
(none)
Defines a directory where hardcopy files will be placed.
If unset, hardcopys are dumped in screen’s current working
directory.
