Shell Programming and Scripting

Got it, but suppose that changes - I will many different time/date stamps in my input file.

In your sample, there is always an empty line after two lines that need to be merged, is that always the case in the real file?

Here is an alternative to try:

Code:

tr -d '\r' < infile | awk '1;{print NF?FS:RS}' ORS=

Hi Scrutinizer, yes - always an empty line. Tried the alternative but no changes.

Strange. Could you take a couple of (anonymized) lines of your input and run it through od -c and post the result?

Code:

head -7 infile | od -c

does this make sense?

It does, but I see neither carriage returns, nor empty lines, only line feeds. So it seems to deviate from your original input sample..

If your input is always like this then you would only need something like:

Code:

sed 'N;s/\n/ /' infile

hi, that works - thanks! Weird though. When I look at my infile with notepad++ I see cr and lf's...

Thank you very much!
