This should (hopefully) do:

Code:

sed ':a $s/\n/\\n/g;N;ba' <<< "$output"

PS:
It is not the same thing. The quoted version did get rid of all the newlines and concatenated the string to one line without leaving any whitespace. The unquoted version replaced the newline with a space.

Thank you very much !

Code:

$newoutput=qx(sed ':a \$s/\\n//g;N;ba' <<< "$newoutput"

The above is what ended up working.

Is it embedded in perl?
In perl you can modify a variable with builtins:

Code:

$newoutput =~ s/\n/\\n/g;
