If on Solaris, use /usr/bin/nawk or /usr/xpg4/bin/awk

The solution to give full path of awk command is working fine.

But the output only get displayed on the screen and not adding it in the file.

I would like the line should get added after the below line in a operational file.
Code:
</font> </b></font></span><p>

Code:
bash-3.00$ /usr/xpg4/bin/awk -v a="$d" -v b="$h"  '/<\/font> <\/b><\/font><\/span><p>/
{$0=$0"\n<span class=\"text\"> " a " CEST Server " b " was restarted due to outofmemory. <br></span>"}1' abc.html >abc1.html

If i redirect output to same abc.html file,the file becomes empty and if i redirect it to some other file suppose abc1.html,the file contains following output. I would like the same operational file should get aapended with the following line.
Code:
<span class="text"> Sat Jul 17 11:17:34 CEST 2010 CEST Server  was restarted due to outofmemory. <br></span>

Output Of abc1.html
Code:
</font> </b></font></span><p>
</font> </b></font></span><p>
<span class="text"> Sat Jul 17 11:17:34 CEST 2010 CEST MARS Server weba1-mars was restarted due to outofmemory. <br></span>

By awk, you have to redirect the output to a temp file, and rename it back.

Hello rdcwayx,

Thanks for the update,

My requirement is the text which i am going to update in operational file will be in some file xyz. Suppose abc file conatins this text
Code:
(<span class="text"> Sat Jul 17 11:17:34 CEST 2010 CEST Server was restarted due to outofmemory. <br></span>)

The above text from "abc" file should get appended after a line (</font> </b></font></span><p>) in "xyz" file.

Try and adapt the following script :
Code:
awk '
BEGIN {
   itext   = "Server was restarted due to outofmemory.";
   itextRe = "span class=\"text\">[^<>]*" text "[[:space:]]*<br></span>";
   otextRe = "</font> </b></font></span><p>";
}
NR==FNR {
   if (match($0,itextRe))
      out = substr($0, RSTART, RLENGTH);
   next;
}
1
$0 ~ otextRe {
   if (out) print out;
   out = "";
}
' cool.abc cool.xyz

Input file abc
Code:
<span class="text">aaaa</span>
sssssssssssss
<span class="text"> Sat Jul 17 11:17:34 CEST 2010 CEST Server was restarted due to outofmemory. <br></span>
<span class="text">end</span>

Input file wyz:
Code:
text text text text
</font> </b></font></span><p>
another text another text another text
</font> </b></font></span><p>
blablablabla

Output:
Code:
text text text text
</font> </b></font></span><p>
span class="text"> Sat Jul 17 11:17:34 CEST 2010 CEST Server was restarted due to outofmemory. <br></span>
another text another text another text
</font> </b></font></span><p>
blablablabla

Jean-Pierre.
