append text to a file in Unix

nandinir · #1 (**permalink**) 12-07-06, 17:12

I need to know if we can append a text to a an existing file in Unix.
If I'm in test.sql which has abcd in it
and
filename.sql has wxyz
I used esc : r filename.sql which will append filename.sql to test.sql but at the beginning
wxyz
abcd

Is there a way I can do it at the end..
as

abcd
wxyz

or simply copy wxyz and paste it in test.sql.
Does anyone has any idea?

esc : $ r filename.sql

extracts from man pages:

Code:

editing commands of the form:

          [ address [ , address ] ] command [ arguments ]

--- snip, snip ---

     Addresses are constructed as follows:

     1.  The character "." addresses the current line.

     2.  The character "$" addresses the last line of the buffer.

     3.  A decimal number  n  addresses  the  n-th  line  of  the
         buffer.

--- snip, snip ---


      Max Address      Command                 Description
     _________________________________________________________________
           2        r rfile          Read  the  contents  of   rfile.
                                     Place  them on the output...

Hi,

What you're talking about is appending files in a vi session. The lastline mode command 'r' inserts the specified file in the current file starting at the next line from where the cursor is. So if you want the external file to be inserted before the line with 'wxyz' make sure the cursor is on the previous line. If there's no previous line make one and delete it afterwards. If you need to append it to the end of the file go to the last line (or do it like pdreyer shows...)
