Question

I had to add a column on a text file (edit with Notepad++ on Windows), adding an incremental counter.

I’ve wrote my bash-awk script on Ubuntu and used it on the text file imported from Windows. It works fine, but the new column is on a newline and not near other columns.

Even if I pipe sed 's/\r\n//g' the column is on a newline.

Could this be a problem over the different handle on the newline between Unix and Windows or something is wrong with my sed instruction?

Thanks

If your file looks something like this:

col1 col2
col3
col1 col2
col3

Use this to append alternating lines and remove the carriage return:

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

The result will look like:

col1 col2 col3
col1 col2 col3
