Problem with 'sed' command while using HTML tags

Hello,

I am using sed as follows -

sed 's/CONTACT SYSTEMS! Some payments have been rejected/<B><font color="red" size="5.0pt"CONTACT SYSTEMS! Some payments have been rejected</font></B>/' $REPORT_FILE

But while executing this, I am getting the error as -
sed: command garbled

& hence the string is not getting replaced with the replacement string in HTML tags. Please help me in this. I am a newbie to using 'sed'.

I am using 'ksh' shell.

Try to escape the non alphanumeric characters in the sed command.

Regards

I tried but it is not working.

I did like this -

sed 's/CONTACT SYSTEMS! Some payments have been rejected/\<B\>\<font color="red" size="5.0pt"\>CONTACT SYSTEMS! Some payments have been rejected\</font\>\</B\>/' $REPORT_FILE

Still got the same error.

Try this:

Code:
sed 's/CONTACT SYSTEMS! Some payments have been rejected/<B><font color="red" size="5\.0pt"CONTACT SYSTEMS! Some payments have been rejected<\/font><\/B>/' $REPORT_FILE

I've escaped the "/" and ".".

Regards

Escaping the "." shouldn't be necessary in the replacement string -- it's the "/" characters that were causing the problem because sed uses them to separate the regexp and the replacement in
Code:
sed  "s/foo/bar/"

If you can't be bothered to escape all the "/"s, you can just as easily use a different character i.e. the above is equivalent to
Code:
sed  "s,foo,bar,"

(I find this useful when using sed on Unix path names.)

Also, you can use "\0" in the replacement string to repeat the matched pattern, e.g.
Code:
sed  "s,CONTACT SYSTEMS! Some payments have been rejected/<B><font color="red" size="5.0pt"\0</font></B>,"

Or use a different separator.
Code:
sed 's%CONTACT SYSTEMS! Some payments have been rejected%<B><font color="red" size="5.0pt"CONTACT SYSTEMS! Some payments have been rejected</font></B>%' $REPORT_FILE
