Why can't I save a VI file after entering data?

Hear is how we use it.
How do I use the vi text editor?
The vi text editor has three modes: command mode, input mode, and ex mode.
Command mode
When starting, vi begins in command mode. If you are ever unsure which mode you're in, press Esc to return to command mode. In command mode, you can move around with the arrow keys, or by using the vi movement keys, as follows:
h left j down k upl right
Several vi commands are listed in the table below:
CommandAction Ctrl-bGo back one page Ctrl-fGo forward one page xDelete the character the cursor is on Shift-xDelete the character before the cursor ddDelete the current line Shift-dDelete everything from the cursor to the end of the line uUndelete a line you just deleted Shift-uUndo all changes to the current line Shift-z-zSave your file and exit the vi editor
Note: In command mode, you can type a number before pressing a command key to repeat the command multiple times. For example, to delete eight lines from the cursor position, you could press 8 and then type dd .
Input mode
The input mode lets you insert or append text. To insert text before the cursor's current position, in command mode, press i . Similarly, to append after the cursor, you can type a . Remember that you can't move around with the cursor keys in this mode. When you're done entering text, press Esc to go back to command mode.
Ex mode
The ex mode is an extension of command mode. To get into it, press Esc and then : (the colon). The cursor will go to the bottom of the screen at a colon prompt. Write your file by entering :w and quit by entering :q . You can combine these to save and exit by entering :wq . However, if you're finished with your file, it's generally more convenient to type Shift-z-z from command mode.
For a more thorough list of vi command keys, see A quick reference list of vi editor commands.
Hope this works.

trans
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
