Command CH - change archive parameters
This command can be used with most of archive modification switches to modify archive parameters. It is especially convenient for switches like -cl, -cu, -tl, which do not have a dedicated command.
It is not able to recompress, encrypt or decrypt archive data and it cannot merge or create volumes. If used without any switches, 'ch' command just copies the archive data without modification.
If used with -amr switch to restore the saved archive name and time, other archive modification switches are ignored.
