Read the error output of the sed command in shell script

In case the sed command below fails I want the reason of its failure i.e. error output should also be added as part of the email. How it can be done?

Code is :

sed -e  abc.txt > /net/abc.com/test/abc.txt

#Sending email

if [ -f /net/abc.com/test/abc.txt ]; then
       echo "content of abc.txt saved to server" | mail -s "Content of abc" [email protected]
else
       echo "File does not exist"
fi

After "File does not exist" reason of the failure of sed should be appended.

The sed command sends its errors to (surprisingly enough) standard error. So you can catch it and treat it specially, as per the following transcript:

pax> echo hello | sed 's/missing/terminator' >outfile 2>errfile

pax> cat outfile

pax> cat errfile
sed: -e expression #1, char 20: unterminated `s' command
