In a c-shell (or tcsh) and from it's command line you could do this:

Method-A:

sed -e ' \
s/} /&\\
/g' < yourfile

Note: Make sure nothing follows the backslashes not even a space or a
TAB or any character because you are escaping the newline. The two
backslashes are there since one required the sed command itself while
the other one is used to escape the newline.


Method-B:
This is in case you dont want to embed a hardcoded newline.

sed -e 'G;:a' -e 's/} \({.*\)\(\n\)/}\2\1\2/;ta' -e 's/.$//' <
yourfile

Hi, thank you everyone for so many solutions. :-)
