I have a file with a lot of lines with a singer number like the
following:
111
222
333
444
555
6666
77777
888
9999
..........
How could I join 3 lines at a time and with a "," in between and at
the beginning of the next line, as in the following:
111,222,333
,444,555,6666
,77777,888,9999
Is this Unix/Linux? Then do a simple:
perl -0777 -pe 's/\n/(++$n%3)?",":"\n,"/eg' lines.txt > commas.txt
if your file is 'lines.txt'.
In Win32, you have to change the quotes.
