Shell Programming and Scripting

Hi all you Unix/Linux gurus,

So, I have something strage going on and need a sanity check...

I have 2 files that both contain 3 lines of text...

File1 - called t:

Code:

CN66270E90
94:57:a5:d3:db:aa
94:57:a5:d3:db:ab

File2 - called tt:

Code:

hostname
5.7.2.7
72:8C:36:3B:5A:17

I want to join the three lines into one... I have a solution to this that works great on file 2 (tt) but not file1 (t) and wanted to know why...

If I run:

Code:

cat t |sed 'N;N;s/\n/,/g'

I get:

Code:

,94:57:a5:d3:db:ab

But, if I run that on tt:

Code:

cat tt | sed 'N;N;s/\n/,/g'

Works like a charm:

Code:

hostname,5.7.2.7,72:8C:36:3B:5A:17

There is nothing different about the two files, well, other than the data, but there are 3 alphanumeric lines so the sed command SHOULD work on both files, correct?

Thanks!
Joe

So, there was something different about the two files... The code is automatically generated from another process and there was a crlf at the end of the lines... So, I had to so a

Code:

sed 's/\r//g'

in the stream...

Solved :-D.

Thanks!

Code:

dos2ux < infile | sed 'N;N;s/\n/,/g'

Yeah, that would work too!

Thanks!
