This option can be used during creation of jar file or while updating the jar file. This option specifies the application entry point without editing or creating the manifest file. For example, this command creates Main.jar where the Main-Class attribute value in the manifest is set to Main.
Whether you're moving to a paperless lifestyle, need to scan a document to back it up or email it, want to scan an old photo, or whatever reason you have for making the physical electronic, a scanner comes in handy. In fact, a scanner is essential. But the catch is that most scanner makers don't have Linux versions of the software that they bundle with their devices. For the most part, that doesn't matter. Because there are good scanning applications available for the Linux desktop.
They work with a variety of scanners, and do a good job. Let's take a look at a three simple but flexible Linux scanning tools. Keep in mind that the software discussed below is hardly an exhaustive list of the scanner software that's available for the Linux desktop. It's what I've used extensively and found useful.
It's the default scanner application for Ubuntu and its derivatives like Linux Mint. Simple Scan is easy to use and packs a few useful features. After you've scanned a document or photo, you can rotate or crop it and save it as an image (JPEG or PNG only) or a PDF. That said, Simple Scan can be slow, even if you scan documents at lower resolutions. On top of that, Simple Scan uses a set of global defaults for scanning, like 150 dpi for text and 300 dpi for photos. You need to go into Simple Scan's preferences to change those settings.
It packs a few more features than Simple Scan but it's still comparatively light. In addition to being able to save scans in various image formats (JPEG, PNG, and TIFF), you can also save a scan as a PDF or a. Unlike Simple Scan, gscan2pdf allows you to set the resolution of what you're scanning, whether it's black and white or colour, and paper size of your scan before you click the button. Those aren't killer features, but they give you a bit more flexibility.

You probably know it as an image editing tool. When combined with a plugin called, The GIMP becomes a powerful scanning application. When you scan with The GIMP, you not only get the opportunity to set a number of options (for example, whether it's color or black and white, the resolution of the scan, and whether or not to compress results), you can also use The GIMP's tools to touch up or apply effects to your scans. This makes it perfect for scanning photos and art. Do they really just work?
The software discussed above works well for the most part and with a variety of hardware. I've used Simple Scan, gscan2pdf, and The GIMP with QuiteInsane with three multifunction printers that I've owned over the years—whether using a USB cable or over wireless.
They've even worked with a Fujitsu ScanSnap scanner. While Simple Scan, gscan2pdf, and The GIMP didn't have all the features of the ScanSnap Manager software (which is for Windows or Mac only), the ScanSnap did scan documents very quickly.
You might have noticed that I wrote works well for the most part in the previous paragraph. I did run into one exception: an inexpensive Canon multifunction printer. Neither Simple Scan, gscan2pdf, nor The GIMP could detect it. I had to download and install Canon's Linux scanner software, which did work. Scanning on the Linux desktop can be easy.
And there's a lot of great software with which to do it. What's your favourite scanning tool for Linux? Share your pick by leaving a comment.
Originally published (in a slightly different form) and reposted via a Creative Commons. The Sane scanner suite (including the XSane frontend scanning application) is excellent.
It can scan to PDF, images, other file types, as well as allow touchup operations and can even do multi-page scanning. It's the most powerful scanning suite for GNU/Linux that I know of. The Sane backend also supports a huge variety of scanners, including a multitude of older scanners that use SCSI connections. In Windows, support for older scanners has been dropped completely especially in new versions of Windows. Thankfully in GNU/Linux we can still use this hardware that still functions just fine.

System File Checker is part of Windows Resource Protection in Windows 10, Windows 8, Windows 7, and Windows Vista, and is sometimes referred to as Windows Resource Checker in those operating systems. System File Checker is part of Windows File Protection in Windows XP and Windows 2000. Important: The sfc command can only be run from the Command Prompt when opened as an administrator. See for information on doing that. Note: The availability of sfc command switches may differ somewhat from operating system to operating system. Sfc Command Syntax Its basic form, this is the required to execute System File Checker options: sfc options =full file path Or, more specifically, this is what it looks like with options: sfc /scannow /verifyonly /scanfile= file /verifyfile= file /offbootdir= boot /offwindir= win /?
Tip: See if you're not sure how to interpret the sfc command syntax as it's written above or described in the table below. /scannow This option instructs sfc to scan all protected operating system files and repair as necessary. /verifyonly This sfc command option is the same as /scannow but without repairing. /scanfile= file This sfc option is the same as /scannow but the scan and repair is only for the specified file.
/offbootdir= boot Used with /offwindir, this sfc option is used to define the boot directory ( boot) when using sfc from outside of Windows. /offwindir= win This sfc option is used with /offbootdir to define the Windows directory ( win) when using sfc offline. Use the with the sfc command to show detailed help about the command's several options. Tip: You can save the output of the sfc command to a file using a. See for instructions or check see for more tips like this. Sfc Command Examples sfc /scannow In the above example, the System File Checker utility is used to scan and then automatically replace any corrupt or missing system files. The /scannow option is the most commonly used switch for the sfc command.
See for more information on using the sfc command in this way. Sfc /scanfile=c: windows system32 ieframe.dll The sfc command above is used to scan ieframe.dll and then repair it if an issue is found. Sfc /scannow /offbootdir=c: /offwindir=c: windows In the next example, protected Windows files are scanned and repaired if necessary ( /scannow) but this is done so with a different installation of Windows ( /offwindir=c: windows) on a different drive ( /offbootdir=c: ).
Tip: The above example is how you would use the sfc command from the Command Prompt in or from a different installation of Windows on the same computer. Sfc /verifyonly Using the sfc command with the /verifyonly option, System File Checker will scan all protected files and report any issues, but no changes are made.
