SYNOPSIS

trans [options] [source]:[target] [text ...]

Translate Shell (trans) is a command-line translator powered by Google Translate (default), Bing Translator, Yandex.Translate, and Apertium. It provides quick access to translation services from the terminal.
Language codes follow ISO 639 standards (e.g., en, fr, de, zh-CN, ja). The source language is auto-detected if not specified. Multiple target languages can be specified by joining codes with +.
Interactive mode (-shell) allows translating line by line. Audio playback requires mplayer, mpv, or mpg123. The tool can also function as a dictionary with the -d flag.

HISTORY

Translate Shell was originally named "Google Translate CLI" and was created by Mort Yao (soimort). It was first released around 2012 to provide command-line access to Google Translate. The project was later renamed and expanded to support multiple translation engines including Bing, Yandex, and Apertium.
