Command line

 

Previous  Top  Next

You can run ARCHPR with command-line parameters. The syntax is:

 

ARCHPR [switches] [zip/arj/ace/rar-filename]

 

or

 

ARCHPR [switches] [axr-filename]

 

The switches are separated with / or - characters. If the switch is followed by some data (e.g., filename, starting password, etc.) which contains these characters: space, semicolon, slash or dash, it must be enclosed in (single or double) quotes.
