usebackq Use the alternate quoting style:
- Instead of double quotes use single quotes for 'Text string to process'
- Use double quotes for long file names in "filenameset".
- Use back quotes for `command_to_process`
command_to_process : The output of the 'command_to_process' is passed into the FOR parameter.
command : The command to carry out, including any parameters. This can be a single
command, or if you enclose it in (brackets), several commands, one per line.
%%parameter : A replaceable parameter:
in a batch file use %%G (on the command line %G)
