sed replacing quotes
Hi!

I'd like to ask for help with the following problem: Using sed all double quotes (") in a textfile should be replaced with two of them ("") but not - and here is my problem - if two are already present ("")...

For example:
"this is an ""sample"" text"

should be
""this is an ""sample"" text""

Thanks for reading and help!

sed
Hi,

Try this one,

Code:
echo "\"this \"\"\"is an \"\"sample\"\" text\"" | sed 's/""/#/g;s/"/""/g;s/#/""/g'

Cheers,

Perl, ok?

Code:
$ cat inputfile
"this is an ""sample"" text"
"this is an ""sample"" text"
$
$ perl -pe 's/(?<!\")\"(?!\")/""/g' inputfile
""this is an ""sample"" text""
""this is an ""sample"" text""
$

Thank you for your replies. The following code from Ranga's suggestion solved this problem.

Code:
echo "\"this \"\"is an \"\"sample\"\" text\"" | sed 's/""/#/g;s/"/""/g;s/#/""/g'

Have a nice weekend!
