Command line reference
Where:
options - options specified in this document. See option rules
sources - files, folders, or URLs identifying input files
configuration-file - zero one or more configurations files
The source parameter specifies the location of image files to read barcodes from. Multiple sources can be specified. Sources can be:
- Local image file
- Local folder
- Web-based image. The source name should start with http://, htpps://
The rules for source values are:
- The value of the source should use UTF-8 to represent non-English file names
- The value containing spaces should be enclosed in double quotes ("")
- Most options are specified as -name=value, except:
- Options with a value described as a flag are specified as -name
- the -d option is specified as -d="macro.name=macro.value"
- If the value is described as a list, zero or more valid values can be set. Multiple values should be separated by a comma (,). No spaces are allowed in the list.
- All options (except -type) are optional.
- A new option value (except -output) replaces the previous value. An empty string value sets the option to its default value.
- For options specifying file names: -output and -output-text.
- If the value contains spaces, it should be enclosed in double quotes ("")
- Environmental and user macro references are expanded at runtime
The order of the options on the command line and in configuration files is important:
- Reader options and source options should be specified before the source parameter. Thus different options can be applied to individual sources.
- Output options that apply to output should be specified before the -output option. Thus, different options can be applied to individual outputs.
Reader options configure the barcode reader parameters to be applied to a source.
Name | Value Description | Default | Valid values |

-type -t | Required. List of barcode types | code39 code128 ucc128 pdf417 qr datamatrix drvlic | code39 code128 codabar ucc128 code93 upca ean8 upce ean13 i25 datamatrix pdf417 qr drvlic imb bpo aust sing 4state patch |
-tbr | List of TBR Codes | 0 | Valid TBR codes for a given type are displayed by the TBR Wizard |
-dir | List of barcode directions | all | all horz vert |
-max-bc -m | A maximum number of barcodes to read on a page. 0 means read all barcodes. | 0 | 0 - 100 |
-timeout | Barcode reading timeout in seconds. 0 means no timeout. | 0 |
|
-encoding | Encoding to convert barcode data to UTF-8 text. See here |
|
|
- Each TBR code set in -tbr option (if more than one) is applied sequentially to each source page. If the number of barcodes found on a page after applying a TBR code from the list is equal to or more than -max-bc value (if set), the rest of the TBR codes are ignored for this page.
If -tbr option is not set, the default algorithm is used. If TBR codes are changed, to return to the default algorithm to the next source set -tbr=0
This option control processing of multi-page file formats: PDF, TIFF, GIF
Name | Value Description | Default | Valid values |
---|---|---|---|
-pages | List of page selectors to limit reading to a set of pages. NMB is an explicit page number (1-based) START is an explicit page number or first STOP is an explicit page number or last CNT is the maximum number of barcodes to detect in a file | all | all even odd first last NMB START-STOP maxbc:CNT |
If the page range is maxbc:CNT and the value of CNT > 0, then file processing stops once CNT barcodes are found.
Setting a barcode count limit might increase overall processing time since multi-threading is disabled.
Images from http://, htpps:// sources are downloaded by the curl command-line application.
- Linux version is installed with the BarcodeReaderCLI.
The curl is invoked with the following default curl options: -s -S -D -m -o -L
- Additional options should be set as needed based on the system requirements.
- BarcodeReaderCLI reports errors returned from the curl.
- To resolve any problems invoke curl from the command line to identify required curl options.
Name | Value Description | Default | Valid values |
---|---|---|---|
-curl-timeout | Total timeout in seconds to download an image with curl. A value of 0.0 disables the timeout. | 15.0 | Floating point number |
-curl-options | Additional curl options. The list of options should be enclosed in the double quotes (""). Use an escape character before any double quotes in the list. |
| |
-curl-no-redirect | Disable request redirect |
|
|
These options control the selection of image files when the source is a folder.
Name | Value Description | Default | Valid values |
---|---|---|---|
-sub -subfolders | Include subfolders of the source folder in the processing | true | true false |
-incl | List of file name masks to be included in the processing | *.tif,*.tiff,*.jpg,*.jpeg,*.pdf,*.bmp,*.png |
|
-excl | List of file name masks to be excluded from processing |
|
|
These options control the output generated by BarcodeReaderCLI.
Name | Value Description | Default | Valid values |
---|---|---|---|
-output -o | File path - output is sent to the specified file. Zero or more output files can be specified, each requires a separate -output option entry console - output is sent to stdout using -format option. |
| File path console |
-format | Console output format, text value requires --output-text option to be specified. | json | json csv text bin |
-output-text | String with macro reference. To define text output in a file, the string should be file://text-file-path, where text-file-path is a template file path. |
|
|
-if-exists | Action to take if the output file already exists: overwrite replaces the existing file append adds new data to an existing file (not allowed for bin output) unique adds a unique file index to the filename before the extension error generates a runtime error | overwrite | overwrite append unique error |
-fields | For barcodes Fields to output in json and csv output. Fields values are obtained through macro expansion except: barcode outputs all default fields | text,data, length,type
| barcode |
-fields | For Driver License Barcodes: Fields to output in json and csv output. Fields values are obtained through macro expansion except: drvlic outputs all default fields. | last,first,middle,dob,eyes,hair, sex,height,weight, street,city,state,postal,id,issued, expires | |
| | | |
Name | Value Description |
---|---|
-help -h | Flag to output command-line help to console. No processing is done. |
-silent -s | Silent mode flag. Do not output the BarcodeReaderCLI version and information |
-timeout | Execution timeout in seconds. The default value of 0.0 disables the timeout. Error is returned if total execution time exceeds timeout. |
-d | Command line use macros. The format is -d="macro.name=macro.value" |
A configuration file is a convenient way to define a set of options and/or sources shared by multiple systems or sessions. For example, they can be used to:
- Define macros specific to a system, such as the location of source or output files.
- Define reader options applied to sources specified on a command line.
Zero or more configuration files can be set on the command line. Multiple files are processed in the order of appearance. The format rules for configuration files are:
- -name sets command line flags
- -name=value sets command line options with values
- source specifies the location of image files to read barcodes from. It can be an image file, a folder containing image files, or a URL. Values with spaces should be enclosed in double quotes ("some text")
- # starts the comment portion of a line. If # is the first character, the whole line is treated as a comment.
- exit ends the processing of a configuration file. The rest of the file is ignored.
- The configuration file should be in UTF-8 to include non-English file names.
