Code:

<Connection^M
                        companyId="TCS"^M
                        connectionMode="client"^M
                        name="TCS_TEMP"^M
                        protocolVersion="4.2"^M
                        disableLogging="false"^M
</Connection>

<Connection^M
                        companyId="HCL"^M
                        connectionMode="client"^M
                        name="HCL_RSDC02"^M
                        protocolVersion="4.2"^M
                        disableLogging="false"^M
</Connection>

<Connection^M
                        companyId="SCB"^M
                        connectionMode="server"^M
                        name="SCB_ERSDC02"^M
                        protocolVersion="4.1"^M
                        disableLogging="false"^M
                        connectionIntervals="08:00:00,18:00:00"^M
                        connectAtStartup="true"^M

</Connection>
<Connection^M
                        companyId="SAT"^M
                        connectionMode="client"^M
                        name="SAT_RSDC02"^M
                        protocolVersion="4.0"^M
                        disableLogging="false"^M
</Connection>

I have the above content in one file. if i grep for name="SCB_ERSDC02" it should display the corresponding block from <Connection^M until </Connection>.
Any commands...?

Code:

output should be
 
<Connection^M
                        companyId="SCB"^M
                        connectionMode="server"^M
                        name="SCB_ERSDC02"^M
                        protocolVersion="4.1"^M
                        disableLogging="false"^M
                        connectionIntervals="08:00:00,18:00:00"^M
                        connectAtStartup="true"^M

</Connection>

Use nawk or /usr/xpg4/bin/awk on Solaris.

Code:

awk '
/<Connection/{i=0}
{a[++i]=$0}
/SCB_ERSDC02/{f=1}
/<\/Connection>/ && f {for(j=1;j<=i;j++){print a[j]};exit}
' file

hi,

Is there any way to pass "SCB_ERSDC02" as command-line arg.

B'cos when i pass its not giving any output.

Save this script, make it executable with chmod:

Code:

#!bin/sh

awk -v var="$1" '
/<Connection/{i=0}
{a[++i]=$0}
$0 ~ var {f=1}
/<\/Connection>/ && f {for(j=1;j<=i;j++){print a[j]};exit}
' file

and call the script as follow:

Code:

./scriptname SCB_ERSDC02

Place the parameter within single quotes:

Code:

./scriptname 'name="SCB_ERSDC02"'
