NAME

       translate - translate a text or web page

SYNOPSIS

       translate {-? | -v | --list-services}

       translate [-s services] [-f lang] [-t lang] {-l}

       translate [-s services] [-f lang] [-t lang] {http_url | https_url}

       translate [-s services] [-f lang] [-t lang] [--max-threads=n] [--max-retries=n] [file]

DESCRIPTION

       translate translates a text or web page.

       If the first synopsis form is used, translate prints a quick help, the version information or the list of
       available translation services to standard output.

       If  the  second  synopsis form is used, translate prints the list of available language pairs to standard
       output.

       If the third synopsis form is used,  translate  translates  the  web  page  pointed  to  by  http_url  or
       https_url,  and  prints  the URL of the translated web page to standard output (http_url must be a string
       starting with http://, and https_url must be a string starting with https://).

       If the fourth synopsis form is used, translate translates the text contained  in  file,  and  prints  the
       translation  to standard output (if file is omitted or given as a single dash, standard input is used in‐
       stead).

OPTIONS

       -?, --help
              Prints a quick help to standard output.

       -v, --version
              Prints version information to standard output.

       --list-services
              Lists the available translation services.

       -s services, --services=services
              Specifies the translation services to use. The services argument must be a comma-separated list of
              service names (default value: all the available services).

              The list of services determines the available language pairs. The order of the list is  important,
              as libtranslate iterates over the list until the requested translation can be performed.

       -l, --list-pairs
              Lists the available language pairs.

              The  -f and -t options can be used to specify a source and/or destination language filter. If nei‐
              ther -f nor -t is specified, all the pairs are listed.

       -f lang, --from=lang
              Specifies the source language of a translation. The lang argument must be a RFC 3066 language  tag
              such as en or zh-TW (default value: see Language Selection).

       -t lang, --to=lang
              Specifies the destination language of a translation. The lang argument must be a RFC 3066 language
              tag such as en or zh-TW (default value: see Language Selection).

       --max-threads=n
              Specifies the maximum number of concurrent threads to use for translating text (default value: 8).

       --max-retries=n
              Specifies the maximum number of retries per text chunk (default value: 3).

LANGUAGE SELECTION

       Definitions:  in this section, default_from is defined as the contents of the environment variable TRANS‐
       LATE_DEFAULT_FROM, or, if that variable is not set, en; default_to is defined as the contents of the  en‐
       vironment variable TRANSLATE_DEFAULT_TO, or, if that variable is not set, fr.

       If  the source language is not specified, it defaults to default_from, or, if the destination language is
       equal to default_from, default_to.

       If the destination language is not specified, it defaults to default_to, or, if the  source  language  is
       equal to default_to, default_from.

CHARACTER SET HANDLING

       Internally, libtranslate uses the UTF-8 encoding.

       If  the  input  text is not encoded in UTF-8, translate assumes it is encoded in the character set of the
       current locale, and attempts to convert it to UTF-8. If the conversion fails, translate exits with an er‐
       ror.

       The output text is converted to the character set of the current locale before printing.

EXAMPLES

       In the following examples, it is assumed that TRANSLATE_DEFAULT_FROM is set to es and that  TRANSLATE_DE‐
       FAULT_TO is set to de.

       translate -f fr -l
              Lists all the available language pairs where the source language is French.

       translate document1
              Translates  the  contents  of  the  file document1 from Spanish to German and prints the result to
              standard output.

       translate -s babelfish,freetranslation document1
              Translates the contents of the file document1 from Spanish to German, only using  the  Babel  Fish
              and FreeTranslation services, and prints the result to standard output.

       translate -f de document1
              Translates  the  contents  of  the  file document1 from German to Spanish and prints the result to
              standard output.

       echo "Le problème est résolu." | translate -f fr -t en
              Translates the text given on standard input from French to English and prints the result to  stan‐
              dard output.

       translate -t en http://www.freebsd.org/es/index.html
              Translates the web page pointed to by http://www.freebsd.org/es/index.html from Spanish to English
              and prints an URL pointing to the result to standard output.

DIAGNOSTICS
