Replace newline in a string
I have a string like below:

{\rtf1\fbidis\ansi\deff0{\fonttbl{\f0\fnil\fcharset0 MS Sans Serif;}{\f1\fnil MS Sans Serif;}}


\viewkind4\uc1\pard\ltrpar\lang2057\f0\fs16 19/11/2010 SOME DESCRIPTION. \par


\lang1033\f1\par


}


I have to replace the newline character with null in the string and also the string \f0\fs16 to \f0\fs20

Could anyone please suggest?

Please note that sed will remove the newline in pattern space so you have read all the lines first using condition as below:
Code:
sed -e ':a;N;$!ba;s/\n/ /g;s/f0\\fs16/f0\\fs20/g'

The string will come in second column in double quotes

Below is the file

"09/22/2009 12:12:11.","{\rtf1\ansi\deff0{\fonttbl{\f0\fswiss Helv;}{\f1\fnil MS Sans Serif;}}
{\colortbl ;\red0\green0\blue0;}
\viewkind4\uc1\pard\cf1\lang1033\f0\fs20 22.09.09
}
","17487","FILE REVIEW"

I have to replace the second string and provide the output as


"09/22/2009 12:12:11.","{\rtf1\ansi\deff0{\fonttbl{\f0\fswiss Helv;}{\f1\fnil MS Sans Serif;}}{\colortbl ;\red0\green0\blue0;}\viewkind4\uc1\pard\cf1\lang1033\f0\fs20 22.09.09
}","17487","FILE REVIEW"

Looks like you want to remove newlines except before the last line. Is this correct ?
I didn't come with nicer solution.
Hope it helps:
Code:
sed -e ':a;N;$!ba;s/\n/ /g;s/f0\\fs16/f0\\fs20/g;s/\(.*\)}/\1\n}/;'

It matches with your input & output sample.

Thanks greet_sed for your constant support however I am getting the below error and I have chaged record separator as pipe

sed: The label :a;N;$!ba;s/\n/ /g;s/f0\\fs16/f0\\fs20/g;s/\(.*\)}/\1\n}/; is greater than eight characters.

You are correct about my requirement
