changing colomn to the line
I have a file which has only one colomn of numbers,ex:
122
173
292
400
979
2152
2339
2376
2387
2446
2450

What ksh / unix command should I use to create a file in which those numbers will be in one line,like this
122 173 292 400 979 .... etc

Thanks a lot for help

why exactly do you need 'cat' here?

You can even do that using...

echo `cat filename`

It should work.

Hi Vgresh,

tr works on strings that input is being provided by cat command.

I dont think i can write like tr "\n" " " filename.

If iam wrong, Please correct me.

Thanks
