Greetings,
I have a file with contents something like

1#data1
data2#
2#data3#
3#data4#

How can I replace the '#' at the end of each line with something like
'||'.
Here the data section might contain some newline characters which I
want to ignore

So the output should be

1#data1
data2||
2#data3||
3#data4||

Any would be appreciated.

TIA

sed 's/#$/||/'

The dollar character matches at the end of line.
