sed command, make multiple lines into one
SmilieHi,

I'm relativley new at unix so am having difficulties at the most basic of areas. I am trying using sed to make multiple lines into one line.

For example, i would like:

Mary
had
a
little
lamb

to look like this
Maryhadalittlelamb

so far i have tried

Code:
sed 's/\n//' file1  > file2

and also
Code:
 sed 's/\
//' file1 > file2

Neither have worked sofar. Does anyone have any suggestions on what the correct way to go about this is?
