Then I would like to sort it (removing duplicates) and send the
output to a new window. I tried the following but with no luck
:new +!sort -u
:new +!sort\ -u
:new +%!sort\ -u
:new +:%!sort\ -u
Anyone else have ideas on how to get this behavior to work. It seems
like something vi should be capable of doing - I want to execute a
command on the current buffer and launch it in a new one.
I think, you would have to double the backslashes. But I am not sure,
this does what you want. I would expect it to open a new window and
in the new empty window perform :%sort -u which is not really useful.
The double backslashes didn't seem to work.
This behavior is useful because I want to compare the output before
and after the sort, in 2 separate buffers, so I don't want it to be in
the same window.
The following can serve as a workaround, but seems kludgy. Since you
want to compare the output, you might want to use 'vnew' and surround it
with :diffthis'es.
" exactly as specified: (open new window with results of cmd)
let bufnum=bufnr('.') | let bufdollar=line('$') | exe "new" | call
append(0,getbufline(bufnum,'1',bufdollar)) | %!sort -u
" with diffy goodness
let bufnum=bufnr('.') | let bufdollar=line('$') | diffthis | exe "vnew" | call
append(0,getbufline(bufnum,'1',bufdollar)) | diffthis | %!sort -u
Though diffing doesn't really make sense after sorting. Maybe you just
want the output of one of these (which could replaced the 'sort -u'
portion from above):
" find duplicated lines
%!sort | uniq -D
" find unmatched lines
%!sort | uniq -d
