trans(1) General Commands Manual trans(1)
NAME
trans - translation tool for use with source message catalogs
SYNOPSIS
trans [-c] [-o name] file.msg
OPTIONS
Display comment lines beginning with a dollar sign ($) for translation, in addition to messages. Call the output file name. The default is
output file name is trans.msg.
DESCRIPTION
The trans command assists in the translation of source message catalogs. The command reads input from file.msg and writes its output to
either a file named trans.msg or a file you name on the command line. The command displays file.msg in a multiple window screen that lets
you simultaneously see the original message, the translated text you enter, and any messages from the trans command. This multiple window
screen is easier to use for translating messages than a single window screen.
The top window in the multiple window screen displays the text in the message source file file.msg. The editor displays the current message
in reverse video.
In the center window, trans displays a prompt that asks you to enter a translated message. You use a control key editor to move the cursor
and delete text in the center window. The control key sequences are defined as follows:
------------------------------------------
Key Sequence Meaning
------------------------------------------
CTRL/k Display control key help
CTRL/h Back space
CTRL/l Forward space
CTRL/w Back word
CTRL/f Forward word
CTRL/e Move to end of input
CTRL/b Move to beginning of input
CTRL/n Next line
CTRL/p Previous line
CTRL/u Delete input
CTRL/i Insert mode (default)
CTRL/r Replace mode
DEL Delete previous character
------------------------------------------
If you need to span more than one line with the translated text, type a backslash () and press the RETURN key to enable line continuation.
After you finish entering the translated text, press the RETURN key to signal that you have finished translating that message.
The bottom window displays any messages generated by trans. If an error occurs, trans prompts you to re-enter the entire line, including
the message label or number.
RESTRICTIONS
Your terminal must be 80 columns by 24 lines for trans to display its three-window screen.
You cannot interrupt a trans session and restart it at the point you stopped. You must complete the all the changes to a file before exit-
ing a file.
