Execution problems with the jar -tvf command and "if" logic
Hi,

I am reading a directory that has a list of jar files. I am searching these files for specific keywords. What i would like to do is write the address of the jar file to a new file if the search result is returned as false. For example;

Code:
 
/home/user/JarDirectory/Examplefile.jar

is the file i am searching.


Code:
 
 
cat $JarDirectory | jar -tvf $i | grep -v car

where $i is the current jar file being read.

If the grep -v command returns false i.e. the word "car" was not present in the file, then the address

Code:
 
/home/user/JarDirectory/Examplefile.jar

is written to a new file instead of the actual content of the file itself.

i am currently using an if statement with a test case e.g.

Code:
 
if [ $? -ne 0]
then
"write address of current jar file to Newfile"
fi

However i cannot get the logic right and i keep writing the content of the jar file to a newfile instead of the address of the jar file itself.

Any help would be greatly appreciated.

Apologies in advance if code was not bracketed properly.

package-appclient

package-appclient(1M)					    Application Server Utility					     package-appclient(1M)

NAME

       package-appclient - packs the application client container libraries and jar files

SYNOPSIS

       package-appclient

       Use  the package-appclient command to pack the application client container libraries and jar files into an appclient.jar file. The created
       file is located at appserver_install_dir/lib/appclient/appclient.jar.  The appclient.jar file  provides	an  application  client  container
       package targeted at remote hosts that do not contain a server installation.

       The  appclient.jar archive contains native code and can be used on a target machine that is of similar architecture as the machine where it
       was produced. So, for example, an appclient.jar produced on a Solaris SPARC platform cannot be used on a Windows client machine.

       After copying the appclient.jar file to a remote location, unjar  it to get a set of libraries and jar files in the appclient directory

       After unjarring on the client machine, modify appclient_install_dir/config/asenv.conf (asenv.bat for Windows) as follows:

	 o  set AS_WEBSERVICES_LIB to appclient_install_dir/lib

	 o  set AS_NSS to appclient_install_dir/lib (appclient_install_dirin for Windows)

	 o  set AS_IMQ_LIB to appclient_install_dir/imq/lib

	 o  set AS_INSTALL to appclient_install_dir

	 o  set AS_JAVA to your JDK 1.4 home directory

	 o  set AS_ACC_CONFIG to appclient_install_dir/config/sun-acc.xml

       Modify appclient_install_dir/config/sun-acc.xml as follows:

	 o  Ensure the DOCTYPE file references appclient_install_dir/lib/dtds

	 o  Ensure that target-server address attribute refrences the server machine.

	 o  Ensure that target-server port attribute refrences the ORB port on the remote machine.

	 o  Ensure that log-service references a log file; if the user wants to put log messages to a log file.

       Modify appclient_install_dir/bin/appclient (appclient.bat for Windows) as follows:

	 o  change token %CONFIG_HOME% to appclient_install_dir/config
