How to re-show this vim’s welcome screen

You can do set number to show the line number at the beginning of each line. However, in original vi, there doesn't seem to be an option to show the current column.

There is a way to at least position the cursor at a specific column. Do 25| to position the cursor at column 25 of the current line.

One of the reasons for that behaviour will be the setting of the terminal for each user.

For example:

• User1 is using TERM=xterm, in this case when you exit vim it will clear the terminal.
• User2 is using TERM=vt100, in this case when you exit vim it will not clear the terminal.

Check what terminal user1 is using with echo $TERM and set the same for user2. for bash:

TERM=xterm; export TERM
