Mac Jones from New Zealand, created this great bash script that scans pages<\/a> from your scanner, then turns them into a PDF. Well, I took that script, and improved upon it. Check it out.<\/p>\n

<\/p>\n

– Producer option for your name
\n– Output folder, with temp files in \/tmp
\n– Device selection (since scanimage picks up my TV tuner as the default scanner), if more than one devices exists
\n– Resolution options
\n– Page size options (since my default was like post card size on my scanner), including a “custom size”
\n– Progress bar for scanning (however, does not show “progress” at the moment)
\n– And an option to restart with a new document<\/p>\n

I am not a bash script expert, and I just whipped this together. There may be better ways to do things… just let me know<\/p>\n
