Appending Consecutive lines

pondlife · #1 (**permalink**) 07-11-2004

Hi,

I have a file containing a single field on every row. What I need is to append one on to the end of another, e.g.

The input file looks like this:

nnnnn
mmmmmm

nnnnn
mmmmmm

I need it to look like this:

nnnnn mmmmmm

nnnnn mmmmmm

Any ideas would be much appreciated, Thanks

Try...

paste -d" " - - < infile > outfile

Or...

awk -v RS="" '{$1=$1};1' infile > outfile

Hi Ygor,

Thanks for this. The paste command is the one that works for me. The awk script outputs just one consecutive line but this might be how I've created my file...

Cheers, pondlife.

Dear Ygor;

For the AWK command.....

If my input file contains....

Code:

nnnnnnnn
mmmmmmmmmmmmmm

nnnnnnnn
mmmmmmmmmmmmmm

nnnnnnnn
mmmmmmmmmmmmmm

I use the command

Code:

awk 'BEGIN{RS="\n\n"} {printf("%s %s\n", $1, $2)}' infile > outfile

to produce the output

Code:

nnnnnnnn mmmmmmmmmmmmmm
nnnnnnnn mmmmmmmmmmmmmm
nnnnnnnn mmmmmmmmmmmmmm

Cheers
ZB

zazzybob,

Does this work on your file?

awk -v RS="" '{$1=$1};1' infile

Yes it does - I'm not too sure how the OP has his file constructed - I constructed mine exactly as per his original post.
