AWK, reformating single line file into one line output

[ErrolDC]

Hi everyone. I want to read a file that consists of single line entries and output them as one line, space seperated. Text and file manipulation is not my best skill. Can someone point me in the right direction? Is AWK the tool I need? Any examples?

sorry, what I meant was multi-line into single line output

Any chance you could post some input samples and expected result as your request is quite vague.

Hope This Helps, PH.

Sure. The is a list of oracle instances. One instance per line. I want to feed them into the korn shell so as to create an array.

So, if the file looks like

foo1
foo2
foo2

I need it reformated as:

foo1 foo2 foo3

Thanks

One way:
tr '\012' ' ' < /path/to/input > output
Another way:
awk 'BEGIN{ORS=" "}1' /path/to/input > output

Hope This Helps, PH.

awk '{ printf("%s",$0) }' input.txt > output.txt

Or

paste -s -d " " input >output

Option Meanings

[tt]-s[/tt]: Normally, [tt]paste[/tt] joins corresponsing lines of several files. This tells it to join lines sequentially.

[tt]-d " "[/tt]: Normally, [tt]paste[/tt] separates fields with a tab character. This tells it to use a space as a delimiter instead.

Chacalinc's suggestion worked for me. I did %s\t because I needed some sort of space to substitute for the newline

Thanks everyone
