PROGRAM:

NAME

trans - Google Translate served as a command-line tool

SYNOPSIS

trans [OPTIONS] [SOURCE]:[TARGETS] [TEXT]...

DESCRIPTION

This tool uses Google Translate to translate text into any language.

Each command-line argument which is not a valid option is treated as TEXT to be
translated.

If neither TEXT nor the input file is specified by command-line arguments, the program
will read and translate from standard input.

OPTIONS

Information options
-V, -version
Print version and exit.

-H, -help
Print help message and exit.

Print details of languages and exit. When specifying two or more language codes,

Display options
-verbose
Verbose mode.

Show the original text and its most relevant translation, then its phonetic
notation (if any), then its alternative translations (if any) or its definition in
the dictionary (if it is a word).

This option is unnecessary in most cases since verbose mode is enabled by default.

Brief mode.

Show the most relevant translation or its phonetic notation only.

Show the definition of the original word in the dictionary.

-identify
Language identification.

Show the identified language of the original text.

Show original text or not. (default: yes)

-show-original-phonetics Y/n
Show phonetic notation of original text or not. (default: yes)

-show-translation Y/n
Show translation or not. (default: yes)

-show-translation-phonetics Y/n
Show phonetic notation of translation or not. (default: yes)

This option is enabled in dictionary mode.

-w NUM, -width NUM
Specify the screen width for padding.

This option overrides the setting of environment variable $COLUMNS.

-theme FILENAME
Specify the theme to use. (default: default)

-no-theme
Do not use any other theme than default.

Audio options
-p, -play
Listen to the translation.

You must have at least one of the supported audio players (mplayer, mpv or mpg123)
installed to stream from Google Text-to-Speech engine. Otherwise, a local speech
synthesizer may be used instead (say on Mac OS X, espeak on Linux or other
platforms).

-speak Listen to the original text.

-player PROGRAM
Specify the audio player to use, and listen to the translation.

Option -play will try to use mplayer, mpv or mpg123 by default, since these players
are known to work for streaming URLs. Not all command-line audio players can work
this way. Use this option only when you have your own preference.

This option overrides the setting of environment variable $PLAYER.

-no-play
Do not listen to the translation.

Terminal paging and browsing options
-v, -view
View the translation in a terminal pager (less, more or most).

Specify the terminal pager to use, and view the translation.

This option overrides the setting of environment variable $PAGER.

-no-view
Do not view the translation in a terminal pager.

-browser PROGRAM
Specify the web browser to use.

This option overrides the setting of environment variable $BROWSER.

Networking options
-x HOST:PORT, -proxy HOST:PORT
Use HTTP proxy on given port.

This option overrides the setting of environment variables $HTTP_PROXY and
$http_proxy.

-u STRING, -user-agent STRING
Specify the User-Agent to identify as.

This option overrides the setting of environment variables $USER_AGENT.

Interactive shell options
-I, -interactive, -shell
Start an interactive shell, invoking rlwrap whenever possible (unless -no-rlwrap is
specified).

-E, -emacs
Start the GNU Emacs front-end for an interactive shell.

This option does not need to, and cannot be used along with -I or -no-rlwrap.

-no-rlwrap
Do not invoke rlwrap when starting an interactive shell.

This option is useful when your terminal type is not supported by rlwrap (e.g.
emacs).

I/O options
-i FILENAME, -input FILENAME
Specify the input file.

Source text to be translated will be read from the input file, instead of standard
input.

Specify the output file.

Translations will be written to the output file, instead of standard output.

Language preference options
-l CODE, -hl CODE, -lang CODE
Specify your home language (the language you would like to see for displaying
prompt messages in the translation).

This option affects only the display in verbose mode (anything other than source
language and target language will be displayed in your home language). This option
has no effect in brief mode.

This option is optional. When its setting is omitted, English will be used.

This option overrides the setting of environment variables $LANGUAGE, $LC_ALL,
$LANG and $HOME_LANG.

-s CODE, -sl CODE, -source CODE
Specify the source language (the language of original text).

This option is optional. When its setting is omitted, the language of original

translated into English.

This option overrides the setting of environment variables $LANGUAGE, $LC_ALL,
$LANG and $TARGET_LANG.

[SOURCE]:[TARGETS]
A simpler, alternative way to specify the source language and target language(s) is
to use a shortcut formatted string:

· SOURCE-CODE:TARGET-CODE

· SOURCE-CODE:TARGET-CODE1+TARGET-CODE2+...

· SOURCE-CODE=TARGET-CODE

· SOURCE-CODE=TARGET-CODE1+TARGET-CODE2+...

Delimiter ":" and "=" can be used interchangeably.

Either SOURCE or TARGETS may be omitted, but the delimiter character must be kept.
