Here is the code in the shell script I have used

sed 's/xyxx/$date1/' /u001/Scripts/abc.html > /u001/Scripts/abc.html

The code is trying to print HTML tags inside AWK command

nawk 'BEGIN{

      FS=","

      print "<HTML>""<HEAD>""<p>Hi All,<br><br>There are no cases closed on the"

      print  "xyxx that meet the criteria for submission</p>"

      }

      END{

      print "<p>Regards,<br>Support Team</p></BODY></HTML>"

      }

      '

I need to replace xyxx with value of date1 inside the file or can I use print command itself inside awk

use sed -i to edit files in place. Your command will not work, because redirections are done first. So you'll be ending up with an empty file.

Also, if you need variable replacement, you need to put the sed command in double quotes for bash to expand the variables.

In this command,

sed 's/xyxx/$date1/' /u001/Scripts/abc.html > /u001/Scripts/abc.html

the redirection happens first! So the shell opens /u001/Scripts/abc.html for writing and empties it. Then the sed command runs, but the input file is empty, so no output either.

As the comments suggest, you should use:

sed -i.bak 's/xyxx/'"$date1"'/' /u001/Scripts/abc.html

which will

create a backup file with extension .bak and overwrite the original file (-i.bak)

and use the variable value of $date1, because it's put in double quotes, unlike the rest of the sed expression.

make sure that $date1 does not contain characters that are interpreted by sed, e.g. a slash or an @ will cause problems.
