Hi Dendany83,

Another option if the text you want to replace always contains 2 lines:
Code:
cat inputfile
begin this is
this is ...................
that is.................
begin this is
-------------------------------------------------------------------------------------------------
text1="Device          |            IPMB0-A              |             IPMB0-B"
text2="Board      Address      |Sent      SentErr      %Errr      |Sent      SentErr      %Errr"
 
sed "s/^begin.*/$text1\n$text2/" inputfile
Device          |            IPMB0-A              |             IPMB0-B
Board      Address      |Sent      SentErr      %Errr      |Sent      SentErr      %Errr
this is ...................
that is.................
Device          |            IPMB0-A              |             IPMB0-B
Board      Address      |Sent      SentErr      %Errr      |Sent      SentErr      %Errr


Hope this helps,

Regards

It is giving an error:
Code:

The idea is that i want to add this header in place of each blank line.

Hi Dendany83,

Maybe trying with awk:
Code:
awk '{
a="        Device          |             IPMB0-A              |             IPMB0-B              "
b="Board      Address      |Sent      SentErr      %Errr      |Sent      SentErr      %Errr      "
c="=============================================================================================="
}
{print ($0~/^$/)?(a"\n"b"\n"c):$0}' 2.log

        Device          |             IPMB0-A              |             IPMB0-B              
Board      Address      |Sent      SentErr      %Errr      |Sent      SentErr      %Errr      
==============================================================================================
           9a            60        36           60.0       60        0            0.0
           96            60        35           58.3       55        0            0.0
           92            60        60           100.0      60        60           100.0
           8e            60        35           58.3       60        0            0.0

           96            60        20           33.3       54        0            0.0
           92            60        60           100.0      60        60           100.0
           8e            60        20           33.3       60        0            0.0


If 2.log file contains more than one consecutive blank line and you want to have the same output as above
add cat -s before awk command.
Code:
cat -s 2.log | awk '< code >'

Hope this helps.

Regards
