printing

[SAM_24]

Hi,

I want to print following lines

line1
line2
line3

as

line1 line2 line3.

I want to print in a single line instead of three lines.

Any help is appreciated.

Thanks.

Hi:

I assume the lines reside in a file. Thus:

# cat filename|xargs

If not, then consider:

# echo "line1\nline2\nline3"|xargs

Regards!

Create a script with:

#! /bin/sed -nf

H
$ {
x
s/\n//g
p
}



Example (script caled join.sed):

join.sed yourfile

Hi,
if it is just a matter of translating carriage return characters into spaces, tr is fast, e.g.:
# tr "\012" "\040" < linefile

Geoff,

May I ask why it is not working if I don't use
H and x commands with s/\n//g?

Thanks a lot.

Here's a couple of alternatives:

cat file_name | paste - - -

(use - for each column needed)

pr -3 -t file_name

(in this case, each line is arranged vertically rather than horizontally)

Well...the H means - Append the contents of the pattern space to the hold space.

The x means - Exchange the contents of the pattern and hold spaces.

I don't know sed enough to explain it...

Here's a handy site:
