To execute an operating system command from within vi, just type for example
Code:
:!ls -l /tmp<CR>

You can also fork a subshell with
Code:
:sh<CR>

---------- Post updated at 07:57 ---------- Previous update was at 07:54 ----------

You can also send the current contents of the vi editor buffer through a filter program with
Code:
1G!Gtr -d ' '<CR>

1G ... to go to the first line
!G ... send everything from the current position up to the last line through the following command
tr -d ' ' ... the tr command to delete spaces
<CR> ... to terminate the command sequence

@rogerben: please don't change a question to a totally different one while it has already been answered. Editing should be done to clarify an existing question, not to ask another one. In the latter case, either ask it in the thread if you feel there is a relationship or in a different thread where it would get a better visibility.

Hi Rojer,

Hope your query is answer by now but I would also like to point you towards the use of
Code:
screen

command

This screen command creates a new screen under a same window and it acts as if there are 2 sessions running.

Try this screen concept and revert back if it helps you cause.
