Adobe Reader Command Line Reference

You can find something about this in the Adobe Developer FAQ. (It's a PDF document rather than a web page, which I guess is unsurprising in this particular case.)

The FAQ notes that the use of the command line switches is unsupported.

To open a file it's:

AcroRd32.exe <filename>

The following switches are available:

• /n - Launch a new instance of Reader even if one is already open
• /s - Don't show the splash screen
• /o - Don't show the open file dialog
• /h - Open as a minimized window
• /p <filename> - Open and go straight to the print dialog
• /t <filename> <printername> <drivername> <portname> - Print the file the specified printer.

Open a PDF file with navigation pane active, zoom out to 50%, and search for and highlight the word "batch":

AcroRd32.exe /A "zoom=50&navpanes=1=OpenActions&search=batch" PdfFile
