Information updated for Tesseract-4.0.0-beta-1
See the [man](https://github.com/tesseract-ocr/tesseract/blob/master/doc/tesseract.1.asc) page for command line syntax and other details.
## tesseract --version
```
tesseract 4.0.0-beta.1-207-g984a
leptonica-1.76.0
libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8 : libopenjp2 2.3.0
Found AVX
Found SSE
```
## tesseract --help
```
Usage:
tesseract --help | --help-extra | --version
tesseract --list-langs
tesseract imagename outputbase [options...] [configfile...]
OCR options:
-l LANG[+LANG] Specify language(s) used for OCR.
NOTE: These options must occur before any configfile.
Single options:
--help Show this help message.
--help-extra Show extra help for advanced users.
--version Show version information.
--list-langs List available languages for tesseract engine.
```
## tesseract --help-extra
```
Usage:
tesseract --help | --help-extra | --help-psm | --help-oem | --version
tesseract --list-langs [--tessdata-dir PATH]
tesseract --print-parameters [options...] [configfile...]
tesseract imagename|imagelist|stdin outputbase|stdout [options...] [configfile...]
OCR options:
--tessdata-dir PATH Specify the location of tessdata path.
--user-words PATH Specify the location of user words file.
--user-patterns PATH Specify the location of user patterns file.
-l LANG[+LANG] Specify language(s) used for OCR.
-c VAR=VALUE Set value for config variables.
Multiple -c arguments are allowed.
--psm NUM Specify page segmentation mode.
--oem NUM Specify OCR Engine mode.
NOTE: These options must occur before any configfile.
Page segmentation modes:
0 Orientation and script detection (OSD) only.
1 Automatic page segmentation with OSD.
2 Automatic page segmentation, but no OSD, or OCR.
3 Fully automatic page segmentation, but no OSD. (Default)
4 Assume a single column of text of variable sizes.
5 Assume a single uniform block of vertically aligned text.
6 Assume a single uniform block of text.
7 Treat the image as a single text line.
8 Treat the image as a single word.
9 Treat the image as a single word in a circle.
10 Treat the image as a single character.
11 Sparse text. Find as much text as possible in no particular order.
12 Sparse text with OSD.
13 Raw line. Treat the image as a single text line,
bypassing hacks that are Tesseract-specific.
OCR Engine modes:
0 Legacy engine only.
1 Neural nets LSTM engine only.
2 Legacy + LSTM engines.
3 Default, based on what is available.
Single options:
-h, --help Show minimal help message.
--help-extra Show extra help for advanced users.
--help-psm Show page segmentation modes.
--help-oem Show OCR Engine modes.
-v, --version Show version information.
--list-langs List available languages for tesseract engine.
--print-parameters Print tesseract parameters.
```

## Using LSTM Engine with Tesseract 4.0alpha
## Using LSTM Engine with Tesseract 4
Use --oem 1 for LSTM, --oem 0 for Legacy Tesseract
Use `--oem 1` for LSTM, `--oem 0` for Legacy Tesseract. Please note that Legacy Tesseract models are only included in traineddata files from [tessdata](https://github.com/tesseract-ocr/tessdata) repo.
`tesseract input.tiff output --oem 1 -l eng`
