In vi  J  that s Shift   J  or  join should do what you want  for the most part  Note that they adjust whitespace  In particular  you ll end up with a space between the two joined lines in many cases  and if the second line is indented that indentation will be removed prior to joining   In Vim you can also use gJ  G  then Shift   J  or  join   These will join lines without doing any whitespace adjustments   In Vim  see  help J for more information

Shift J removes the line change character from the current line  so by pressing  J  at any place in the line you can combine the current line and the next line in the way you want

Vi or Vim   Anyway  the following command works for Vim in  nocompatible  mode  That is  I suppose  almost pure vi    join    If you want to do it from normal command use  gJ   With  gJ  you join lines as is -- without adding or removing whitespaces   S lt Switch ID gt  F lt File type gt   ID lt ID number gt  T lt date time gt  O lt Original File name gt  DAT   Result   S lt Switch ID gt  F lt File type gt  ID lt ID number gt  T lt date time gt  O lt Original File name gt  DAT   With  J  command you will have   S lt Switch ID gt  F lt File type gt   ID lt ID number gt  T lt date time gt  O lt Original File name gt  DAT   Note space between type gt  and  ID

Another way of joining two lines without placing cursor to that line is    6 6s  n     Here 6 is the line number to which another line will be join  To display the line number  use  set nu   If we are on the cursor where the next line should be joined  then    s  n     In both cases we don t need g like  s  n  g  because on one line only one  n exist

Just replace the   n  with      In vi Vim for every line in the document    s  gt  n   gt   g   If you want to confirm every replacement    s  gt  n   gt   gc
