In Vi can you merge every two lines


like


i
have
to
go
to
the
market

becomes

i have
to go
to the
market


Here, I think subsitituing the end of the statement with carriage
return should help .

The -n option is often more powerful, but here it works without -n:

sed '$p;N;s/\n/ /' file

With vim:

%s/\n\(.*\n\)/ \1/

With vi:

:%!paste -sd ' \n' -

or

:%!paste -d ' ' - -

(that one might add a trailing " " on the last line).

Note that there's a newgroup to discuss about vi: comp.editors.

Neither of them work.
is there some mistake or something missing

Quoted context is missing; in the first place.

Michael is correct, you can use "sed" and it will work.

Other options:

#-- define a "vi" macro to do it for you.
#-- press the following keys exactly, case sensitive (except <esc>
means the single Escape key, of course)
OJj<esc>0"mD

#-- then position your cursor on the first line of the data you want
to "pair up", then press
[at] m
#-- if that works to your satisfaction, then try holding down the [at]
key for five seconds or so...


#------------------ You may also try this:

xargs -L 2 echo <orig.txt>new.txt

or if you are in "vi" already goto the top of the file, and type:

!G xargs -L 2 echo

#------------------ You may also try this:
#-- this will put your data in two wide columns, evenly spaced
pr -2 -t

#-------- or even a 'quicky' shell script fragment, like
while { read ONE; read TWO ; } ;do
echo $ONE $TWO
done < orig.txt > new.txt

#------- Though Michael's solution should also work, of

sed -n '$p;N;s/\n/ /;p' < old.txt > new.txt

#-------- even a goofy little awk script, like

awk '{if(two != "") {print one, two; one="";two=""} else { two=one;
one=$0 } }' < old.txt > new.txt

:g/^/,+j

With an odd number of lines there will be an error message, but you
can just ignore it.

With vim (no vi available to check) you can avoid the error message by

:1,$-1g/^/,+j

which seems to work with even and odd number of lines.
