Unix Tip #4458- May 26, 2017

SHELL OUTPUT INTO VI


In VI editor you can get
the output of any shell
command command inserted
into the file you are
editing by using:

:r!

For example:

:r!who -r

inserts the ouput of the
command "who -r" to the
file currently being
edited.

This can be effectively used
to copy the contents of a
file to the file currently
being edited

ie,

:r!cat /etc/passwd

inserts all the contents of
the the /etc/passwd to the
file currently being edited.
