Shell Programming and Scripting

Hi folks,

I need to append line or bulk of lines into a file.
For example,I have the following section in opmn.xml file:
<process-type id="OC4J_RTEadmin_NIR" module-id="OC4J">
<module-data>
<category id="start-parameters">
<data id="java-options" value="-server -Djava.security.policy=/home/ias/v10.1.2/j2ee/OC4J_RTEadmin_NIR/config/java2.policy -Djava.awt.headless=true"/>
<data id="oc4j-options" value="-properties"/>
</category>
<category id="stop-parameters">
<data id="java-options" value="-Djava.security.policy=/home/ias/v10.1.2/j2ee/OC4J_RTEadmin_NIR/config/java2.policy -Djava.awt.headless=true"/>
</category>
</module-data>
<start timeout="900" retry="2"/>
<stop timeout="120"/>
<restart timeout="720" retry="2"/>
<port id="ajp" range="3301-3400"/>
<port id="rmi" range="3201-3300"/>
<port id="jms" range="3701-3800"/>
<process-set id="default_island" numprocs="1"/>
</process-type>

I need to do the following:
1. Locating the line number of the string : id="OC4J_RTEadmin_$SCHEMA_NAME" (no problem with me).
2. Under this string ,finding the line number of the string <port id="jms" range="3701-3800"/> (no problem with me).
3. After the line number from paragraph 2 ,inserting the following lines:
<environment>
<prop name=\"LD_LIBRARY_PATH\" value=\"${ORACLE_HOME}/lib\"/>
<prop name=\"SHLIB_PATH\" value=\"${ORACLE_HOME}/lib32\"/>
</environment>

Is it possible to do it with sed command?

Thanks in advance,
Nir

It would be better if you could put the input within the code tags for better readability.

The way sed is used in this case is,

Code:

sed '/search_string/r FILE' inputfile

where FILE has the contents of the which needs to be inserted after you find, the search_string.

I am continuing on the solution provided the other day by r2007.

Code:

sed '/process-type id="'"$SCHEMA_NAME"'"/,/<\/process-type>/{ /<port id="jms".*/r ENV_FILE; }' inputfile

Not tested tho'.

ENV_FILE contains

Code:

<environment>
<prop name=\"LD_LIBRARY_PATH\" value=\"${ORACLE_HOME}/lib\"/>
<prop name=\"SHLIB_PATH\" value=\"${ORACLE_HOME}/lib32\"/>
</environment>

Hi vino,

Thanks a lot!
I'm at home now,so I'll test it tomorrow and let you know.

Bye for now,
Nir

Hi vino,

I ran the following command:

Code:

sed '/process-type id="'"$SCHEMA_NAME"'"/,/<\/process-type>/{ /<port id="jms".*/r foo.lst; }' opmn.xml

and I got the following error:
sed: -e expression #1, char 0: Unmatched `{'

opmn.xml=inputfile
foo.lst=ENV_FILE

Thanks in advance,
Nir

Code:

sed -e '/process-type id="'"$SCHEMA_NAME"'"/,/<\/process-type>/p' 
-e '/<port id="jms".*/r foo.lst' opmn.xml

Hi vino,

Thanks again.
The command runs now but it appends the lines in the wrong place.

The section looks now:
<process-type id="OC4J_RTEadmin_NIR" module-id="OC4J">
<module-data>
<category id="start-parameters">
<data id="java-options" value="-server -Djava.security.policy=/home/ias/v10.1.2/j2ee/OC4J_RTEadmin_NIR/config/java2.policy -Djava.awt.headless=true"/>
<data id="oc4j-options" value="-properties"/>
</category>
<category id="stop-parameters">
<data id="java-options" value="-Djava.security.policy=/home/ias/v10.1.2/j2ee/OC4J_RTEadmin_NIR/config/java2.policy -Djava.awt.headless=true"/>
</category>
</module-data>
<start timeout="900" retry="2"/>
<stop timeout="120"/>
<restart timeout="720" retry="2"/>
<port id="ajp" range="3301-3400"/>
<port id="rmi" range="3201-3300"/>
<port id="jms" range="3701-3800"/>
<environment>
<variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/>
<variable id="SHLIB_PATH" value="/home/ias/v10.1.2/lib32" append="true"/>
</environment>
<process-set id="default_island" numprocs="1"/>
</process-type>

The bulk was inserted after jms line.
I wanted to insert the lines right after the string :
process-type id="OC4J_RTEadmin_$SCHEMA_NAME"

It should be as the following:

<process-type id="OC4J_RTEadmin_NIR" module-id="OC4J">
<environment>
<variable id="LD_LIBRARY_PATH" value="/home/ias/v10.1.2/lib" append="true"/>
<variable id="SHLIB_PATH" value="/home/ias/v10.1.2/lib32" append="true"/>
</environment>
<module-data>
<category id="start-parameters">
<data id="java-options" value="-server -Djava.security.policy=/home/ias/v10.1.2/j2ee/OC4J_RTEadmin_NIR/config/java2.policy -Djava.awt.headless=true"/>
<data id="oc4j-options" value="-properties"/>
</category>

Request you again to always put your input code/sample with the code tags. Helps in reading better.
