In my example I gave 3 lines but it can be anything between 1 and 20 lines.
In this case you will have to have some indication for a "record" being complete. Maybe you will need some record starting criteria too, for which one could match. Provide some data and i will provide some solution.

This is just a way to enter non-printing (control-) characters into vi: enter input mode, press "CTRL-V", then press CTRL-M (for example for "^M"). You should be still in input mode and see "^M" under the cursor.

Quote:
sed 's/.$//' does remove the ^M at the end of each line but then it is still a multi-line format.
It removes the last character in a line, regardless which character this is - this is the problem. You have to specifically match "^M" (CTRL-M) and throw that out. You can throw out linefeeds by searching for "\n". Try the following with some test file:

Code:
sed 'N;s/\n/@/' /some/file

to see the effect: two lines combined to one and the linefeed is replaced by an at.

[quote]Is there a way to find out in VI what is the ascii value of the character under the cursor ?[/qoute]

No, but you can use "od -ax <file> | more".

I hope this helps.

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. SEE ALSO
