scanadf

scanadf [options]

Control scanners with an automatic document feeder (ADF), which can return multiple documents. The images are written to output files specified by the --outputfile option. scanadf uses the SANE interface to access the scanner and can support any device for which there is a SANE backend.

Options

-d device, --device-name device

Specify a SANE device name. The default is to attempt to open the first available device.

-e num, --end-count num

Specify the last page number to scan.

-h, --help

Print help message and exit. You can get device-specific help by running scanadf as follows:

scanadf -h -d device

-L, --list-devices

Display a list of available devices. The list may not be complete, particularly when accessing scanners across the network. Only scanners listed in a configuration file (typically in the directory /etc/sane.d) are displayed. A scanner with no configuration file entry must be accessed by its full device name.

-o string, --output-file string

Specify a format string used to generate the output filename. Use %d replacement to insert the current page number in the name. The default format string is image-%04d.

-r, --raw

Write raw image data to the output file without attempting to interpret it. Usually used together with --scan-script.

-s num, --start-count num

Specify the page number of the first scanned image.

-S name, --scan-script name

Specify the name of a script to run after each image is scanned.

-v, --verbose

Run in verbose mode, providing additional status messages.

-V, --version

Print version information and exit.
