Hi,
I need to append to previous line all the line not starting by 2005, here is a example :
2005abcdefghij .....
1234567 ....
2005abcdefghij .....
The result should be
2005abcdefghij ..... 1234567
2005abcdefghij .....
Apparently, sed command could help for that :
sed -e :a -e '/$!N;s/\N2005/ /;ta' -e ...
But I don't know exactly how to do that ...
Please help !
Tks

sed -e ': a {N;s/$2005.*\n$$2005.*$/\1\n\2/;s/$2005.*$\n$.*$/\1\2/;s/\n\n/\n/;b a}'
... assuming no blank lines.
